Vowels and
consonants are outlined in the tables below.
Vowels Nepali distinguishes six oral vowels and five
nasal vowels. /o/ does not have a phonemic nasal counterpart, although it is often in
free variation with [õ]. Nepali has ten
diphthongs: /ui̯/, /iu̯/, /ei̯/, /eu̯/, /oi̯/, /ou̯/, /ʌi̯/, /ʌu̯/, /ai̯/, and /au̯/.
Consonants [j] and [w] are nonsyllabic
allophones of [i] and [u], respectively. Every consonant except [j], [w], and /ɦ/ has a
geminate counterpart between vowels. /ɳ/ and /ʃ/ also exist in some loanwords such as /baɳ/ "arrow" and /nareʃ/ "king", but these sounds are sometimes replaced with native Nepali phonemes. The
murmured stops may lose their breathy-voice between vowels and word-finally. Non-geminate
aspirated and murmured stops may also become fricatives, with /pʰ/ as
ɸ], /bʱ/ as
β], /kʰ/ as
x], and /ɡʱ/ as
ɣ]. Examples of this are /sʌpʰa/ 'clean' becoming [sʌɸa] and /ʌɡʱaɖi/ 'before' becoming [ʌɣaɽi]. Typically, sounds transcribed with the retroflex symbols ⟨
ʈ, ʈʰ,
ɖ, ɖʱ, ɽ, ɳ, ɽ̃⟩ are not purely retroflex
ʈ, ʈʰ,
ɖ, ɖʱ,
ɽ,
ɳ, ɽ̃] but apical postalveolar
t̠, t̠ʰ,
d̠, d̠ʱ,
ɾ̠,
n̠, ɾ̠̃]. Some speakers may use purely retroflex sounds after /u/ and /a/, but other speakers use the apical articulation in all positions. Final schwas
may or may not be preserved in speech. The following rules can be followed to figure out whether or not Nepali words retain the final schwa: • Schwa is retained if the final syllable is a conjunct consonant. (, 'end'), (, 'relation'), (, 'greatest'/a last name).Exceptions: conjuncts such as in (, 'stage') (, 'city') and occasionally the last name (/). • For any verb form the final schwa is always retained unless the schwa-cancelling halanta is present. (, 'it happens'), (, 'in happening so; therefore'), (, 'he apparently went'), but (, 'they are'), (, 'she went'). Meanings may change with the wrong orthography: (, 'she didn't go') vs (, 'she went'). • Adverbs, onomatopoeia and postpositions usually maintain the schwa and if they don't, a halanta is required: ( 'now'), (, 'towards'), (, 'today') ( 'drizzle') vs (, 'more'). • Few exceptional nouns retain the schwa such as: (, 'suffering'), (, 'pleasure'). Note: Schwas are often retained in music and poetry to add extra syllables when needed. == Grammar ==
