noun / verb
smear
SMEER/smɪr/
A messy coating spread across a surface.
He leaves a broad smear of red paint across the white board.

Etymology
Smerian described rubbing on oil or ointment, but also coating something too thickly with a sticky substance. That second use already contains the messy spreading expressed by smear today.
In context
