Morphology

big + sister

The meaning 'an older female sibling' is directly derivable from combining 'big' (used in family contexts to mark relative age/greater size) with 'sister' (female sibling); the adjective+noun composition transparently signals an older sibling. This usage is common and cross-linguistically accessible, so a B1 learner who knows the constituents will readily infer the intended familial meaning.

Etymology

Big sister brings a simple picture: an older, often taller girl who looks after or helps a younger child. The word big here means 'older' and sister is the female sibling, so it means 'an older female sibling'.
