A verb that needs an object to complete its meaning is called a transitive verb.
He kicks the football.
If we say, he kicks
Then, the following question comes in our mind what does he kick?
And without an answer to this question, the verb can’t complete its meaning. So the verb kicks need an object.
•He told me a joke
•Nadia rings the bell
•He plays football
•He sang a song
An intransitive verb is a verb that doesn’t need an object to complete its meaning.
He laughs loudly
Here, the verb ‘laughs’ doesn’t demand any object to complete its meaning.
Therefore, the verb ‘laughs’ is called an intransitive verb.
