ᵵ

T with middle tilde ( ᵵ ) is a letter of the Latin script. At present, there is no uppercase version encoded in Unicode.

It is used in the International Phonetic Alphabet for a velarised or pharyngealised voiceless alveolar stop. However, the use of a middle tilde to mark velarisation or pharyngealisation was deprecated by the International Phonetic Association in 1989, and the symbol is often avoided.^[1][2] As of 2025^[update], the IPA uses a superscript velar fricative to mark velarisation (yielding [tˠ]) and a superscript pharyngeal approximant to mark pharyngealisation (yielding [tˤ]).^[3]

For velarized articulations we use ˠ (02E0 MODIFIER LETTER SMALL GAMMA), for pharyngealized articulations we use ˤ (02E4 MODIFIER LETTER REVERSED GLOTTAL STOP)
