Morphology

green + thumb

The components 'green' (associated with plants) and 'thumb' (a body part suggesting manual ability) provide a clear metaphorical cue that relates to gardening skill, so learners could plausibly infer the domain. However, the exact conventionalized meaning 'a natural talent for making plants grow' is idiomatic and not fully predictable without exposure; different languages use different metaphors (e.g. 'green fingers' in British English), so this is only partially transparent.

Etymology

The idiom green thumb may come from gardeners whose thumb actually became green from touching plants and leaves, creating a strong picture of hands busy with gardening. That's why the phrase means 'a natural ability to make plants grow'.
