“沾满烂泥”可以翻译为 “caked/covered in mud” 或 “smeared with mud”。
“caked/covered in mud”：侧重于描述物体表面被泥紧紧附着、覆盖的状态，强调泥的附着程度较深、较厚，给人一种物体被泥完全包裹、难以清理的感觉。例如：The boots were caked in mud after the long hike.（经过长途徒步后，靴子上沾满了烂泥 。）
“smeared with mud”：更强调泥以一种涂抹、涂抹不均匀的方式附着在物体上，突出泥的涂抹状态和痕迹。例如：The car wheels were smeared with mud.（汽车车轮上沾满了烂泥 。）
