U+0BA3 "ண" Tamil Letter Nna Unicode Character

U+0BA3 "ண" Tamil Letter Nna is a distinct character in the Tamil script, representing a retroflex nasal consonant sound, pronounced by curling the tongue back to touch the roof of the mouth, similar to the 'n' in the English word "barn" but with a heavier, more retroflex articulation. It is classified as a consonant in the Tamil abugida, where it typically carries an inherent vowel 'a' unless modified by a vowel sign, and it appears in words such as "கண்" (kaṇ) meaning "eye". This character is essential for accurately writing and pronouncing many Tamil words that require this specific retroflex sound, distinguishing it from other Tamil nasal letters like the dental "ந" or the alveolar "ன".
