Meaning
粗大 describes something that is both thick in diameter and large in size. It combines 粗 (thick, coarse) with 大 (big, large) to emphasize the substantial physical dimensions of an object. This word is commonly used for tree trunks, limbs, ropes, poles, and other cylindrical or elongated objects that are impressively thick and heavy.
Usage
粗大 is primarily used as an attributive adjective before nouns, especially for natural or physical objects. It carries a neutral to positive connotation, often suggesting strength or sturdiness. Common collocations include body parts (arms, legs), natural objects (tree branches, roots), and industrial items (cables, pipes). It's more formal than simply saying 很粗 (very thick).
