Morphology

one-off = one (transparent) = off + one

The meaning is directly formed by the compound 'one' + 'off' indicating a single, non-repeated occurrence. [Postprocessing: moved 'off' from base_words to prefix]

Etymology

One-off is made from one and off, where off here means 'separate' or 'not regular'. So a one-off is a single event or thing that happens only once and is not repeated.
