Here is the conjugation of the of the Italian verb graffiare which means to scratch. Cats like to scratch and some people like to annoyingly scratch the blackboard at school. The verb is a regular one, which means it is conjugated like most of the rest of the verbs in Italian that end in ARE.

First person - io graffio (I scratch)
Second person - tu graffi (you scratch)
Third person - lui / lei / Lei graffia (he / she / you (formal) scratches)
First person plural - noi graffiamo (we scratch)
Second person plural - voi graffiate (you all scratch)
Third person plural - loro / Loro graffiano (they scratch / or You all (formal) scratch)

Below is a funny picture that shows an example of the third person plural.

It says beware of the cat and the owner (they scratch!)

Notice how you did not have to use loro - it is implied from the way the verb is conjugated.
