Transitive verbs are action verbs that require an object to receive that action.
For example:
She baked a cake. (She=subject, baked= transitive verb, a cake=object)
I ride the bicycle. (I=subject, rode=transitive verb, the bicycle=object)
You can easily find the object of the sentence, by asking ''what'' (or in some cases ''whom'').
In this case:
What did she bake? A cake = Object
What do I ride? The bicycle = Object
Intransitive verbs, unilike transitive, don't require an object.
For example:
The girl cried. (The girl= subject, cried=intransitive verb)
The train stopped. (The train= subject, stopped= intransitive verb)
You can see that there is no object following these verbs.
Hope that helps!
