Morphology

precompose = compose (semi-transparent) = pre + compose

The prefix 'pre-' still clearly means 'before', but the specialized technical sense of composing on the left is not fully predictable for general learners.

Etymology

The word precompose combines pre- 'before' and compose 'to put together', and in programming it means to join small functions so one runs before the next. So when you precompose operations you make a single step that does the earlier work first, which helps keep the order of actions clear.
