Morphology

birth + defect

The meaning 'an abnormality present at birth' is directly and compositionally derived from 'birth' (the event of being born) plus 'defect' (a flaw or abnormality). This straightforward noun–noun compound follows regular English formation and has clear equivalents in other languages, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Birth defect joins birth (when a baby is born) and defect (a fault or problem) to paint a simple picture: a doctor sees a problem right at the moment of birth. That's why the term means 'an abnormality present in a baby at birth'.
