"I cook the food."
Translation:אני מבשל את האוכל.
Well, אוכל can be either the noun meaning "food" or the verb "to eat" in the present tense as masculine singular (אני אוכל - I eat, אתה אוכל - you (m.) eat, הוא אוכל - he eats). And אכול is the passive participle of the verb to eat and it means "eaten".
So, if you said: האוכל אכול, that would translate to "the food is eaten"
