The word 马厩 (mǎjiù), meaning "horse stable", is a classical Chinese compound noun formed through semantic combination, where the first character 马 (mǎ) meaning "horse" acts as a modifier specifying the type or purpose of the second character 厩 (jiù) meaning "stable" or "shed". This follows the common grammatical structure of modifier-head (like "horse-stable"), where the head noun (厩) denotes the general category and the modifier (马) narrows it down to a specific, functional subset.
