Modifier Letter Capital C

It marks Chatino tone or modifies a symbol in phonetic notation.

As a Chatino tone letter, ꟲ marks lexical tone: the pitch pattern that distinguishes words. In the Quiahije variety, it marks mid tone; the letter-to-tone mapping can differ across Chatino varieties.

Some para-IPA notation—extensions built around the International Phonetic Alphabet (IPA)—uses ꟲ to modify a nearby symbol or stand for a consonant class, a group of sounds. The notation key gives its exact reading.

What should I do if someone sends ꟲ?

Check which writing or transcription system it came from.

In a Chatino word, ꟲ belongs to the tone spelling. In a phonetics example, the notation's key explains its job; the character alone does not identify the system.

The raised-C convention predates computer encoding.

Chatino writing used raised capital letters for tone before ꟲ had a computer encoding. The Unicode proposal cites Chatino material from 2014; older transcriptions also preserve superscript tone letters.
