Nuqta

The nuqta (Hindi: नुक़्ता, Urdu: نقطہ, romanized: nuqtā, IPA: [nʊqt̪aː, nʊkt̪aː]; sometimes also spelled nukta), is a diacritic mark that was introduced in Devanagari and some other Indic scripts to represent sounds not present in the original scripts. It takes the form of a dot placed below a character. This idea is inspired from the Arabic script; for example, there are some letters in Urdu that share the same basic shape but differ in the placement of dots(s) or nuqta(s) in the Perso-Arabic script: the letter ع ayn, with the addition of a nuqta on top, becomes the letter غ g͟hayn.
