enquire: [13] The -quire element in enquire (or inquire, as it is alternatively spelled) is etymologically related to English query and question. The word comes via Old French enquerre from *inquāerere, the Vulgar Latin descendant of Latin inquīrere. This was a compound verb formed from the intensive prefix in- and quaerere ‘seek, ask’. The modern English spelling with i in the second syllable comes from a 15th-century reintroduction of the vowel of Latin inquīrere. Inquest [13] comes from the Latin verb’s past participle.
