Covered in with

Grammar: Condition

A noun followed by だらけ means “covered in” or “full of” that thing. The thing is usually undesirable and scattered throughout the area or object.

Add の and the covered item when it needs to be stated: 泥(どろ)だらけの靴(くつ) (mud-covered shoes).

Usage Notes

だらけ sounds negative or critical. Because it suggests an undesirable abundance, it is not a neutral way to say something is full of good things.
