You use some form of posse, "to be able," plus the infinitive of a verb. For example, if you wanted to say "can sing" ("to sing" = canere), the present tense forms would be:
possum canere - "I can sing"
potes canere - "You [singular] can sing"
potest canere - "He, she, or it can sing"
possumus canere - "We can sing"
potestis canere - "You [plural] can sing"
possunt canere - "They can sing"
It would also be possible to use the verb scire ("to know") instead of posse. This would convey "can" in the sense of "know how to . . .". The forms of scire in the present tense are scio, scis, scit, scimus, scitis, sciunt.
