Palatal hook

N with palatal hook, followed by eng, a palatal nasal and a retroflex nasal for comparison.

The palatal hook (◌̡) is a type of hook diacritic formerly used in the International Phonetic Alphabet to represent palatalized consonants. It is a small, leftwards-facing hook joined to the bottom-right side of a letter, and is distinguished from various other hooks indicating retroflexion, etc. Theoretically, it could be used on all IPA consonant letters except for those for palatal consonants, but it is not attested on all of the IPA letters of its era. It was withdrawn by the IPA in 1989, in favour of a superscript j following the consonant (i.e., ⟨ƫ⟩ becomes ⟨tʲ⟩).

The IPA recommended that esh ⟨ʃ⟩ and ezh ⟨ʒ⟩ not use the palatal hook, but instead get special curled symbols: ⟨ʆ⟩ and ⟨ʓ⟩. However, versions with the hook have also been used and are supported by Unicode.

Palatal hooks are also used for Lithuanian dialectology in the Lithuanian Phonetic Transcription System (or Lithuanian Phonetic Alphabet), including the unusual letter ꞔ, which is not a c plus palatal hook but a graphic variant of ᶃ.
