Morphology

horse + chestnut

This is a straightforward compositional compound where 'horse' modifies 'chestnut' to name a particular kind of chestnut/tree. A B1 learner who knows both words will understand it denotes a type of chestnut (a specific tree/seed); they may not infer details like inedibility, but the basic referent is directly derivable from the constituents.

Etymology

Horse chestnut is called that because its shiny seeds look like real chestnuts but the tree and its nuts are not for eating. One popular story says people once used the seeds for horses, so the word 'horse' marks this as the animal kind and reminds us the nuts are 'not for eating'.
