'Foul' means disgustingly dirty or a sports penalty; 'fowl' refers to domestic birds like chickens or turkeys.
Adjective/noun/verb. Offensively dirty or smelling bad. A violation in sports. In baseball: a ball hit outside the field. Also: to make dirty or commit a violation.
The foul smell from the kitchen drain was coming from a blocked pipe.

Common mistake
"A pen of fouls" when meaning the birds (correct: fowl). "Fowl play" when meaning suspicious or criminal conduct (correct: foul play). 'Foul play' is a fixed phrase meaning suspected crime or unfair conduct.
Trick to remember it
'Foul' has OU like 'out' and 'oust' — things ejected, removed, wrong. 'Fowl' contains OWL — an owl is a bird, and OWL lives inside fOWL.
Quick rule
Is it dirty, bad, or a sports violation? 'Foul'. Are they the domestic or game birds? 'Fowl'.
Did you know?
'Neither fish nor fowl' means something that fits no clear category — a medieval expression when the main food groups were fish, fowl, and flesh (red meat). 'Foul play' in crime contexts implies murder or serious wrongdoing when evidence is ambiguous. In baseball, 'foul ball' comes from 'foul territory' — the areas outside the first and third base lines. The word 'fowl' comes from Old English 'fugol' (bird) — the same root as German 'Vogel' and the name 'Fogelberg'.
