Morphology

inborn + reflex

The phrase combines 'inborn' (present at birth) and 'reflex' (an automatic, unlearned response), so the meaning 'an automatic response present at birth' is directly and transparently derivable from its parts. This compositional structure is common across languages and follows basic English adjective + noun semantics, so a B1 learner who knows both words will readily understand it.

Etymology

Inborn reflex comes from the simple image of a newborn making a quick, natural movement: inborn means born with it and reflex means a fast, automatic action, as when a baby sucks when its lips are touched. So, inborn reflex means a natural 'automatic' response a baby has from birth.
