Morphology

stool + pigeon

The literal constituents ('stool' as a seat or obscurely a decoy and 'pigeon' as a bird) do not transparently yield the sense 'informer'; the idiomatic meaning comes from a historical practice of using a decoy bird and is not inferable from the parts by a typical B1 learner. Even if a learner knew a rare decoy-related sense of 'stool', the shift to ‘secret informant’ is culturally/historically specific and unpredictable.

Etymology

One popular story says stool pigeon was later used for a human informer because, like a fake pigeon that lures other birds, a person who secretly helps the police can lead to trouble for others, so the phrase came to mean 'an informer'.
