Palatal hook

The palatal hook (◌̡) is a type of hook diacritic formerly used in the International Phonetic Alphabet to represent palatalized and prevelar consonants.

[1] The IPA recommended that esh ⟨ ʃ ⟩ and ezh ⟨ʒ⟩ not use the palatal hook, but instead get special curled symbols: ⟨ ʆ ⟩ and ⟨ʓ⟩.

Palatal hooks are also used for Lithuanian dialectology in the Lithuanian Phonetic Transcription System (or Lithuanian Phonetic Alphabet), including the exceptional form ꞔ, which is not a c plus palatal hook but rather a graphic variant of ᶃ once recommended by the IPA.

C with hook, ꞔ, is not a palatal letter but a script variant of ᶃ.

[2] Other non-palatal consonants listed below the chart: Unicode includes a combining character for the palatal hook, but it is not canonically equivalent to the precomposed characters, which should be used instead.
