Morphology

bi-fold + door

The compound is directly interpretable as 'bi-' (two) + 'fold' (to bend) + 'door' — i.e. a door composed of folding panels, typically two. This follows productive English compounding/affixation patterns, so a B1 learner who knows the constituent parts can readily infer the meaning.

Etymology

Bi-fold door comes from bi- meaning 'two' and fold meaning 'to bend', so it names a door made of two panels that bend or fold together. That's why a bi-fold door is used when you want a door that saves space by folding to one side.
