Morphology

at + one + time

The phrase is directly compositional: 'at' marks a temporal location, 'one' specifies a single instance, and 'time' denotes a point or period, so 'at one time' naturally yields 'at a particular (often earlier) time.' This mapping is common across languages (equivalent to 'once' or 'formerly') and would be readily inferable by a B1 learner who knows the constituent words.

Etymology

The adverb at one time comes from the idea of everything happening in one time — one single moment. Imagine all the lights going out together; they go out at one time, so the phrase means 'simultaneously'.
