Morphology

big + mouth

The literal words 'big' and 'mouth' suggest a prominent mouth and thus give a plausible cue to talkativeness, so a learner who knows both constituents could infer the sense 'talks a lot'. However the meaning arises via a metaphorical/metonymic shift (not a literal large mouth) and includes the idiomatic nuance of revealing secrets, so the exact sense is not fully predictable without exposure.

Etymology

The noun big mouth creates an image of someone with a very big mouth that lets words fall out. So it means 'a person who talks too much or reveals secrets'.
