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, – even on those used 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 It was withdrawn by the IPA in 1989, in favour of a superscript j following the consonant (i.e., ⟨ƫ⟩ becomes ⟨tʲ⟩).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 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.

Scope

The palatal hook was introduced in 1921 and officially adopted in 1928. The last published IPA chart to support it was that of 1979. The following consonants appear on that chart. Those attested with palatal hook are bolded and set with the hook; the hooked letters are either in Unicode or are scheduled to appear in Unicode 17. Palatal letters are enclosed in parentheses; they are generally redundant with the hook, though 'palatalized palatals' are described in the literature, and ꞔ occurs in non-IPA usage.

Computer encoding

Unicode includes a combining character for the palatal hook, but it is not canonically equivalent to the precomposed characters, which should be used instead.
