Morphology

latch + on

The verb 'latch' (to fasten) combined with the particle 'on' evokes the metaphor of attaching to or gripping something, so a learner who knows the constituents can reasonably infer a sense of 'grasping' or 'attaching to' an idea. However, the jump from physical fastening to the specific senses 'understand/realize/adopt' is metaphorical and not fully predictable without exposure, so it is only partially transparent.

Etymology

Latch on can also mean understanding or accepting an idea. One popular image is a latch catching a piece of wood. Once it catches, it stays, so the phrase came to mean 'to understand' or 'to accept' an idea.
