feat

the word 'feat' entered english in the late 14th century from the old french 'fait', meaning 'action, deed, achievement'. old french inherited it from the latin noun 'factum', meaning 'a thing done, a deed', which is the neuter past participle of the verb 'facere', 'to do or make'. this latin root is prolific, giving english many words like 'fact', 'factory', and 'manufacture'. the semantic journey is direct: from the general latin concept of 'a thing done', the word specialized in french and english to denote a deed of notable skill, strength, or courage, thus an impressive achievement.

this word is a simplex loanword from french. it is not productively formed from separable morphemes in modern english.
