Morphology

loose + lip

The parts 'loose' (unrestrained) and 'lip' (metonymically for speech/mouth) combine to suggest someone whose speech is uncontrolled, so a learner can plausibly infer 'talkative/indiscreet'. However the mapping from 'lip' to 'speech' and the nuance of revealing secrets is somewhat metaphorical and not fully predictable, so it is only partially transparent. Cross-linguistic parallels (e.g. 'loose tongue') help inference but do not make the meaning wholly compositional.

Etymology

Loose lip comes from the wartime warning 'loose lips sink ships.' The image is simple: a loose lip lets words fall out like water and those words can cause big trouble, so it came to mean 'a person who talks too much or reveals secrets'.
