In the exercise how is "ils" a verb?

Salut Tope,

I'm unclear about which exercise you mean, but ils is a third-person plural subject pronoun.

The subject acts on the object directly or indirectly by using a verb   --  the sentence structure is subject, verb, object (direct/indirect)  in the simplest form.

Please post again if you need further support or clarification.

Bonne continuation

Jim

"Ils" does the action. The person's name has been replaced with a subject pronoun in the third-person plural form.
