aiguiser

Etymology
, from, from , the past participle of. Compare 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬. The initial -ai- can probably be explained through a hypothetical proto-French or late Vulgar Latin intermediate form, from assimilation of the palatal approximant in the second syllable of an earlier. In this hypothesis, the Old French form may be due to influence from  (cf. ).
