Morphology

canker + sore

Both constituents directly contribute to the meaning: 'canker' denotes a painful ulcer and 'sore' denotes a lesion, so together they name a specific type of painful mouth ulcer. This noun‑noun composition is compositional and follows regular English patterns, so a B1 learner who knows both words would be able to infer the MWE's meaning.

Etymology

Canker sore comes from an old word canker that meant a small sore that seemed to 'eat away' the flesh, and sore means a 'painful spot'. So today canker sore names a small, painful sore inside the mouth.
