What is conjugate a verb?

To conjugate a verb means to change a verb to match the object you're talking about.

e.g

1st person singular= I listen

2nd person singular= You listen

3rd person singular= He/She/One/It listens

1st person plural= We listen

2nd person plural= You listen

3rd person plural= They listen

It gets more confusing in other languages where you get tons of irregular verbs that don't follow a simple pattern or the endings are different for each person.
