Morphology

in + one's + bones

The phrase maps a bodily image ('bones') onto an inner, deep conviction, so learners who know the words can access a related physical/visceral sense. However, the leap from a literal location in the body to the specific idiomatic sense of 'intuitive certainty without evidence' is metaphorical and not fully predictable without exposure, making it only partially transparent.

Etymology

In one's bones comes from that same physical image: if you felt something in your bones, you trusted a strong inner sense, so today the phrase means sensing something clearly without any proof.
