Nepal Bhasa uses 36 consonant letters grouped into five varga series โ velar, palatal, retroflex, dental, and labial stops โ plus semivowels, sibilants, and the distinctive gvya letter, a labio-velar consonant unique to Nepal Bhasa that has no equivalent in Devanagari.
Consonants in Nepal Bhasa writing carry an inherent a vowel; adding a vowel sign (matra) above, below, or beside the letter changes it to i, ii, u, uu, e, ai, o, or au.
Nepal Bhasa has 10 independent vowel letters written word-initially or after a virama, when a syllable opens with a vowel rather than a consonant โ a pattern common in native Kathmandu Valley words.
The vowel inventory distinguishes length for a, i, and u (short and long pairs) and includes the diphthongs ai and au, many of which entered Nepal Bhasa through centuries of Sanskrit borrowing.
Nine vowel sign diacritics (matras) attach above, below, or around a consonant to replace its inherent a with aa, i, ii, u, uu, e, ai, o, or au in Nepal Bhasa words.
The virama cancels the inherent vowel entirely to join two consonants into a cluster โ essential for the many Sanskrit-origin words that carry consonant clusters in formal Nepal Bhasa vocabulary.
Traditional Nepal Bhasa numerals (๐โ๐) used in Pracalit manuscripts and cultural texts. The counting words in Nepal Bhasa are: เคถเฅเคจเฅเคฏ (0), เคเคฟเคเฅ (1), เคจเคฟเคเฅ (2), เคธเฅเคตเคเคฌเฅ (3), เคชเคฟเคเคเฅ (4), เคจเฅเคฏเคพเคเฅ (5), เคเฅเคเฅ (6), เคจเฅเคนเคฏเคเฅ (7), เคเฅเคฏเคพเคเฅ (8), เคเฅเคเฅ (9), เคเคฟเคเฅ (10) [4].
The counting word pattern โ many ending in -gu โ is characteristic of Nepal Bhasa and reflects its Tibeto-Burman origins rather than Sanskrit-based counting. Both Pracalit digits and Arabic numerals appear in modern Nepal Bhasa publications.
Nepal Bhasa writing uses the anusvara for nasalisation, the visarga for a final glottal fricative found in Sanskrit loanwords, and the virama to suppress the inherent vowel and join consonants into clusters.
Classical Nepal Bhasa texts close sentences with the danda (single vertical bar) and major sections with the double danda, following the Brahmic punctuation system shared with Sanskrit and other South Asian literary traditions.
