The Devanagari Script

Hindi Consonants

	Stops				Nasals
	Unvoiced		Voiced
	Unaspirated	Aspirated	Unaspirated	Aspirated
Velar	क	ख	ग	घ	ङ

Retroflex	ट	ठ	ड (ड़)	ढ (ढ़)	ण
Dental	त	थ	द	ध	न
Labial	प	फ (फ़)	ब	भ	म

Next, consider the ordering of the same 25 consonants in the Devanagari script, from left to right:

क ख ग घ ङ च छ ज झ ञ ट ठ ड (ड़) ढ (ढ़) ण त थ द ध न प फ (फ़) ब भ म

Note that if you read the chart from left to right and top to bottom, it corresponds to the ordering of the letters in Devanagari! This is remarkable because this has been the ordering of the Devanagari script for centuries. This fact is a testament to the advanced state of the study of phonetics in ancient India.

Ordering of Vowels

The vowels in Hindi are likewise ordered scientifically.

Place of Articulation of Vowels

• Velar/Guttural vowels are pronounced near the back of the throat, as the "a" in "amid".
• Palatal vowels are pronounced with the tip of the tongue raised toward the hard palatte, as the "i" in "sing".
• Labial vowels are pronounced using the lips, as the "oo" in "boot".
• Retroflex vowels are pronounced with the tongue curled backward. There are no retroflex vowels in English.
• Palato-Guttural vowels are pronounced as a combination of palatal and velar articulation.
• Labio-Guttural vowels are pronounced as a combination of labial and velar articulation.

Manner of Articulation of Vowels

The manner of articulation of vowels can be classified according to many categories, but we will discuss two particular categories:

• Short vowels are sustained for a relatively shorter duration of time.
• Long vowels are sustained for a relatively longer duration of time.

Monophthongs are vowels pronounced as a single, pure sound, whereas diphthongs are vowels pronounced as two adjacent sounds glided together within the same syllable.

Hindi vowels

Articulation	Vowels
	Monophthongs		Diphthongs
	Short	Long
Guttural	अ	आ
Palatal	इ	ई
Labial	उ	ऊ
Retroflex	ऋ	-
Palato-Guttural		ए	ऐ
Labio-Guttural		ओ	औ

Now consider the vowels in their order within the Devanagari script:

अ आ इ ई उ ऊ ऋ ए ऐ ओ औ

Once again, note that the ordering corresponds to the ordering in the table, if the table is ordered from left to right and top to bottom.

The technical distinction between the vowel pairs in Hindi (such as इ ई) is the vowel length, although modern Hindi speakers tend to pronounce the vowels distinctly, regardless of the duration. इ is pronounced like the "i" in "bit" whereas ई is pronounced like the "ee" in "feet", and उ is pronounced like the "u" in "put" whereas ऊ is pronounced like the "oo" in "boot".

Also note that the complement of the letter ऋ is marked as "-" because it is not commonly employed in Hindi, but it is used in other applications of Devanagari, such as in Sanskrit.

Miscellaneous Ordering

The final consonants in the Devanagari script are organized into three categories: semivowels/approximants, sibilants, and a glottal.

Application to Hindi

Now, I'll discuss the application of Devanagari to Hindi.

Hindi is written using the Devanagari script.

Devanagari is also used to write other languages, such as Nepali and Marathi, and is the most common script used to write Sanskrit. Several other languages have scripts which are related to Devanagari, such as Bengali, Punjabi, and Gujarati.

The Devanagari script represents the sounds of the Hindi language with remarkable consistency. Whereas many letters of the English alphabet can be pronounced many different ways, the letters of the Devanagari script are pronounced consistently (with a few minor exceptions). Thus, Devanagari is relatively easy to learn.

Devanagari consists of 11 vowels and 33 consonants, and is written from left to right.

Basic Genius

Devanagari is not actually an alphabet, but a so-called alphasyllabary. An alphasyllabary is a writing system which is primarily based on consonants, and in which vowel symbols are requisite yet secondary. As such, the fundamental genius of Devanagari is that every letter represents a consonant which is followed by an inherent schwa vowel, अ. For example, the letter स is read "sa". In order to suppress the inherent vowel, one of two methods is required: a diacritical mark called a halant, or a ligature, called a conjunct. In order to indicate a vowel other than the inherent vowel, diacritical marks called maatraas are used. For vowels independent of consonants, there exist full letters to transcribe vowels.

Vowels

Hindi has 11 vowels. 10 vowels are transcribed in two distinct forms: the independent form, and the dependent (maatraa) form. The independent form is used when the vowel letter appears alone, at the beginning of a word, or immediately following another vowel letter. The dependent form is used when the vowel follows a consonant.

Vowels in Independent Form

अ आ   इ ई   उ ऊ   ऋ   ए ऐ   ओ औ

The following table lists the vowel in its independent form, and its description. The best way to learn the pronunciation is to learn from a native speaker.

Vowels

Vowel	Description
अ	as in "but", "again"
आ	as in father, far
इ	as in "fit", "hit"
ई	as in "feet", "heat"
उ	as in "put", "pull"
ऊ	as in "pool", "shoot"
ऋ	as is "rip", "rib" with the tongue curled back
ए	as in "ate", "day"
ऐ	as in "Khyber"
ओ	as in "go", "boat"
औ	as in "owl"

Vowels in Dependent (maatraa) Form

When a vowel follows a consonant, it is written in its respective maatraa form, which is appended to the consonant. Matraa forms never appear at the beginning of a word or after another vowel. The first vowel, अ, has no particular maatraa form. Instead it is the default vowel. It is assumed to be present unless the maatraa form of another vowel is explicitly appended to a consonant. In Sanskrit, the vowel अ is pronounced at the end of a word. In Hindi, however, it is not pronounced, except at the end of single-letter words. The following table lists each vowel in its independent form, its corresponding dependent form, and how it would appear with the consonant क ("k").

Maatraa Forms of Vowels

Independent	Dependent	With क
अ	(none)	क
आ	ा	का
इ	ि	कि
ई	ी	की
उ	ु	कु
ऊ	ू	कू
ऋ	ृ	कृ
ए	े	के
ऐ	ै	कै
ओ	ो	को
औ	ौ	कौ

Allophones

As mentioned earlier, the distinction between the vowels इ and ई is the duration of the pronunciation of the vowel - the former is shorter, and the latter longer. However, in practice, the vowel इ is pronounced more like the English "i" as in the word "it", as described in the corresponding text. The same is so for the vowels उ and ऊ.

Final Schwa

The schwa, अ, is normally not pronounced at the end of a word. Thus, कान is pronounced "kaan", not "kaana". An exception occurs when a word ends in a conjunct. In this case, the word may be pronounced with a slight final schwa, as in मित्र, literally "mitr", but often pronounced like "mitr(a)", with a soft final schwa.

Monophthongs versus Diphthongs

Native English speakers should be careful not to pronounce the Hindi vowels that are monophthongs as diphthongs. For instance, ओ is a pure sound, not a glide like the English "o" as in the word "low". Many vowel letters in English can represent diphthongs. Thus, whereas English may represent a diphthong with the letter "i" as in the word "site", in Devanagari, this diphthong would be more precisely transcribed as two monopthongs, आ and इ: साइट

Schwa Syncope

Sometimes, the inherent vowel is not pronounced, despite its implicit presence and the lack of any modifying diacritic. This phenomenon is called schwa syncope, or alternatively schwa deletion. For instance, consider the word नमकीन, literally "namakeen". The second inherent vowel is not pronounced, as if the word were written नम्कीन ("namkeen"). There is no rule which can predict this phenomenon with absolute accuracy, yet one generally useful heuristic is that the inherent vowel is deleted after a consonant which is between two vocalic consonants. Thus, the word देवनागरी itself is pronounced with the first schwa deleted, like "Devnagari", and not "Devanagari", even though it is still transliterated as "Devanagari".

Occasionally, the schwa will not be totally deleted, but will be very slightly pronounced.

Schwa Pronunciation in Context

The Hindi inherent vowel, अ, may be pronounced as [ɛ], a vowel which is similar to the English "e" as in the word "bed", but only in certain contexts, namely, when two अ vowels appear on both sides of the consonant ह, as in the verb पहनना ("to wear"). Both schwa vowels are often pronounced as [ɛ] in such circumstances. Thus, although the phrase पहन लो is literally "pahan lo", it is often pronounced "pehen lo". Occasionally, however, this phenomenon occurs when only one schwa vowel is beside the consonant ह, as in the word बहिन ("sister"). In this case, both vowels adjacent to ह are converted to [ɛ], and thus, although the word is literally "bahin", it is pronounced "behen".

Nasalization of Vowels

All vowels in Hindi can be nasalized, except for ऋ. Nasalization is indicated by either the symbol " ं " or by the symbol " ँ ". The former symbol is called bindu ("dot"), and the latter symbol is called chandrabindu ("moon and dot"). The bindu is used when part or all of the vowel symbol extends above the horizontal line. The chandrabindu is used when no part of the vowel symbol extends above the horizontal line. The bindu is more common is modern written Hindi, and may even be used exclusively.

The following examples summarize the use of the bindu and chandrabindu:

अँ आँ इँ ईं उँ ऊँ एँ ऐं ओं औं

कँ काँ किं कीं कुँ कूँ कें कैं कों कौं

A special diacritic is sometimes used with the vowel आ to transcribe the English "o" vowel sound as in "college": कॉलेज

Consonants

Velar Consonants

Letter	Description
क	unaspirated "k"
ख	aspirated "k"
ग	unaspirated "g"
घ	aspirated "g"
ङ	n, as in "sing"

Note that the velar nasal consonant does not appear as the first letter of any word.

Palatal Consonants

Letter	Description
च	unaspirated "ch", as in "cheese"
छ	aspirated "ch"
ज	unaspirated "j"
झ	aspirated "j"
ञ	n, as in "punch"

Retroflex Consonants

Letter	Description
ट	like "t", but retroflex and unaspirated
ठ	like "t", but retroflex and aspirated
ड	like "d", but retroflex and unaspirated
ढ	like "d", but retroflex and aspirated
ण	like "n", but retroflex

Hindi additionally employs two flap consonants: ड़ and ढ़. The symbols for these consonants are formed by placing a diacritical mark called a nuqta, which is a subscript dot, underneath the consonant symbols ड and ढ respectively.

ड़ is pronounced by flapping the tongue from the retroflex position forward, toward the alveolar ridge. ढ़ is pronounced similarly, except with aspiration.

English does have an alveolar flap consonant, as the "t" in the word "better", or the "d" as in "bedding" as in American English. The Hindi flaps are retroflex, however.

Retroflex Flap Consonants

Letter	Description
ड़	like a flapped "d", flapping tongue from retroflex to alveolar ridge position
ढ़	like flapped "d", flapping tongue from retroflex to alveolar ridge position, and aspirated

Dental Consonants

Letter	Description
त	like "t", but dental and unaspirated
थ	like "t", but dental and aspirated
द	like "d", but dental and unaspirated
ध	like "d", but dental and aspirated
न	like "n" in "name", but dental

Labial Consonants

Letter	Description
प	like "p", but unaspirated
फ	like "p", but aspirated
ब	like "b", but unaspirated
भ	like "b", but aspirated
म	"m"

Semivowels

Letter	Description
य	"y", as in "young"
र	like "r", but often rolled
ल	"l", as in "lip"
व	either "w", or "v"

The Hindi "r" sound is typically a flap. However, some speakers may trill the "r" sound occasionally, or may even occasionally pronounce it closer to an unflapped approximant sound, as in the English "r" in "red".

Sibilants

Letter	Description
श	"sh", as in "shave"
ष	like "sh", but retroflex
स	"s", as in "save"

Glottal

Letter	Description
ह	like "h", but voiced

Allophony of "w" and "v" in Hindi

A phoneme is an equivalent class of atomic, discrete sounds which can produce a difference in meaning when spoken, yet cannot produce a difference in meaning when substituted for one another. A "phone" is simply a distinct sound. For instance, in English the "p" in the word "spit" and in the word "pit" are pronounced distinctly: the former is unaspirated, the latter is aspirated. Thus, they are two distinct phones. However, they are both members of the same phoneme, since substituting one for the other can never produce a difference in meaning, even though substitution may be perceived as slightly awkward by native speakers. Two distinct phones which are both members of the same phoneme are called "allophones" (from Greek, "different sounds").

In Hindi, the sounds associated with the English letters "w" and "v" are allophones. Both are transcribed with one letter, व. Analogously to the English example above, these sounds are typically pronounced consistently in words, but they do not constitute meaningful differences in utterances. For example, the word वो is typically pronounced as "vo", whereas the suffix -वाला is typically pronounced "wala". Hindi speakers are not generally aware of this distinction, even though they pronounce the distinction fairly consistently, just as English speakers are not aware of the differences of aspiration in certain letters, yet pronounce aspiration consistently.

Thus, व may be pronounced as "w" or "v". Some speakers may even pronounce an intermediate sound.

Semi-Allophones "j" and "z" in Hindi

Likewise, Hindi speakers do not generally maintain any strict distinction between the English "j" and "z" sounds either, but will typically pronounce words consistently. This situation is not quite the same as "w" and "v", since technically, the "z" sound can be represented distinctly from the "j" sound by placing a dot (nuqta) underneath the letter, and some speakers are aware of this distinction. For instance, the word जो is pronounced as "jo". There is some variation, however, in some words such as ज्यादा - some speakers pronounce this as "zyada", and some as "jyada".

Sibilants

In modern Hindi, both श and ष and pronounced the same. ष occurs mostly in Sankrit loanwords.

English Alveolar Consonants

There is no equivalent of the English "t" or "d" in Hindi. These English sounds are pronounced with the tongue on the tip of the alveolar ridge, behind the top teeth. This place of articulation is between the Devanagari retroflex and dental positions, although the English pronunciation will sound much closer to the retroflex pronunciation to Hindi speakers. English loanwords containing "t" or "d" are therefore transcribed with retroflex approximations.

Capital Letters

Devanagari has no capital letters.

Special Matraa Forms of उ and ऊ with र

र + उ = रु

र + ऊ = रू

Borrowed Sounds

There are 6 additional sounds used in Hindi which have no corresponding symbols in Devanagari. These sounds are represented by placing the nuqta underneath a symbol which is phonetically similar. These symbols represent sounds from other languages, such as Persian, Arabic, and English.

Foreign Sounds

Letter	Approximation
क़	like "k", but pronounced in the back of the mouth
ख़	velar fricative, like "Bach" in German
ग़	velar sound, similar to ख़ but voiced
ज़	just as English "s", as in "is"
झ़	similar to the s in English "vision"
फ़	just as English "f"

Only two of the borrowed sounds are typically pronounced distinctly from the non-nuqta forms, though: ज़़ and फ़
