Morphology

at + length

The phrase combines 'at' (locating in time) with 'length' (a span or duration), so a learner who knows both words can plausibly infer the basic sense 'for a long time'. However, the extended meaning 'in great detail / thoroughly' and the somewhat formal/fixed nature of the adverbial collocation are not fully predictable without exposure, making the relation only partially transparent.

Etymology

The phrase at length may come from the image of stretching something out to its full length. When a story or talk is stretched out like that, it lasts a long time and gives many details, so the phrase means 'for a long time' or 'in great detail'.
