Etymology
The compound adjective 'one-time-only' is a modern English formation built from three native Germanic elements, each with a clear and persistent meaning. 'One' originates from Proto-Germanic 'ainaz', signifying singularity. 'Time' derives from Proto-Germanic 'tīmô', related to the concept of a stretch or period. 'Only' evolved from the Old English 'ānlīc' (one-like), emphasizing uniqueness. The logic of the word is transparently literal: it describes an event or offer that is singular ('one') in its occurrence ('time') and has no possibility of recurrence ('only'), a meaning directly constructed from the sum of its parts.
Analysis
