drowsy

DROW-zee/ˈdraʊzi/

Sleepy and not fully alert.

I feel drowsy after lunch and struggle to stay focused.

A seated man struggles to stay awake, his eyelids half closed and his head drooping into one supporting hand as he yawns.
Etymology

Drowsy probably ultimately comes from a verb meaning “sink” or “become languid or inactive.” That connection suggests sinking into a sluggish state, where sleepiness reduces alertness.
