Editing Grantha script (section)

===Vowels and syllables===
Grantha includes five long vowels, five short vowels, two vocalic consonants, ṛ and ḷ which are treated as vowels and may be short or long, and two part-vowels, ''anusvara'' {{angbr|{{Script|Gran|◌𑌂}}}} ṁ and ''visarga'', {{angbr|{{Script|Gran|◌𑌃}}}} ḥ. Independent vowel letters are used for word-initial vowels. Otherwise, vowels, vocalics, and part-vowels are written as diacritics attached to consonants. Each consonant in Grantha includes an inherent vowel ''a'', so the letter {{angbr|{{Script|Gran|𑌕}}}}, for example, is pronounced ka. Adding a vowel diacritic modifies the vowel sound, so {{angbr|{{Script|Gran|𑌕}}}} plus the diacritic {{angbr|{{Script|Gran|𑌓}}}}, gives the syllable {{angbr|{{Script|Gran|𑌕𑍋}}}}, ''ko''. The absence of a vowel is marked with a [[virāma]] {{angbr|{{Script|Gran|◌𑍍}}}}, for example, {{angbr|{{Script|Gran|𑌕}}}} {{Transliteration|Gran|ISO|ka}} plus {{angbr|{{Script|Gran|◌𑍍}}}} creates an isolated consonant {{angbr|{{Script|Gran|𑌕𑍍}}}} ''k''.

There are a few [[typographical ligature|ligatures]] of consonants with vowel [[diacritic]]s and of consonants with ''virāma''.
