For He/She/It, examples: He wantS to go to the cinema (positive) DoeS He want to go to the cinema? (question) He doeS not want to go to the cinema (negative)

we add s,es or ies to verbs when the verb is in the present simple tense and the subject is third person singular(he/she/it) i use my computer a lot. sam uses his computer a lot. i want a cup of tea. Sarah wants a cup of tea. we watch TV in the evening. he watches Tv in the evening. they study their lessons every day. she studies her lessons every day. i like milk. the cat likes milk.

We use the "s" when a man or woman (other than myself) or thing does something: "I like pizza" vs. "He likes pizza"

I think that it is easier to use English without conjugating verbs. It makes speaking much easier! Of course it makes you a bit harder to understand.
