だらけCovered with or full of
だらけ attaches to a noun and says that something is covered with, full of, or characterized throughout by a large amount of it. It usually suggests that the situation is undesirable.
What it describes
Use だらけ with nouns that can plausibly accumulate, spread, recur, or characterize an entire scene. These include physical substances, visible marks or damage, scattered objects, and abstract problems such as mistakes, lies, contradictions, and debts. The expression presents the amount as widespread rather than giving an exact quantity.
Physical and abstract examples
Coverage versus adhering contamination
With a contaminant such as mud, both 泥だらけ and 泥まみれ can be natural. The first broadly views something as covered in mud or having muddy areas throughout; the second more vividly emphasizes mud adhering to or enveloping the surface. The distinction is a matter of viewpoint, not a strict rule: だらけ also has a much broader range with scattered objects and abstract problems.
