Morphology

built-in = build (transparent) = in + built

The adjective clearly means 'built into' something, so learners who know 'build' and 'in' can usually infer the sense. [Postprocessing: moved 'in' from base_words to prefix]

Etymology

Built-in comes from putting build ('make') together with in ('inside'). This gives a clear image: something 'made inside' the object, not added later, which is why a built-in feature is a permanent part of the thing.
