ενίοτε

Etymology: From Ancient Greek ἐνίοτε (eníote), which is a compound of ἐν (en, 'in') and ὅτε (hóte, 'when'). The term literally means 'in when' or 'at times when', which evolved to mean 'sometimes' or 'occasionally'. This construction reflects how temporal adverbs often develop from prepositional phrases indicating specific points in time.
