Morphology

branched + chain

The meaning is directly and transparently derived from 'branched' (having branches) modifying 'chain' (a linked sequence), so a learner who knows both words can infer a chain with side branches; the technical chemistry sense is just a specific application of this literal composition. This literal modifier+noun pattern is cross-linguistically common and follows standard compositional rules, making it accessible to B1 learners.

Etymology

Branched chain comes from the picture of a main chain with small branches or 'side chains' sticking out, like a tree or a road with side streets. So the name helps you imagine a molecule with a main line of atoms and extra parts attached, which is what a 'branched chain' means today.
