Learn Hardcore Hausa: Wakilin ya samar da tikiti. - The representative provided a ticket.

Wakili is the basic form meaning representative or agent. The ending -n makes it a more specific/determined form, often corresponding to the representative in English. So Wakilin here is naturally understood as the representative or the agent.

Why is there a ya after Wakilin? Doesn’t that look like the representative he?

Yes, literally it can feel that way to an English speaker, but this is normal Hausa grammar. In Hausa, a full subject noun is commonly followed by a matching subject pronoun/TAM marker. So:

Wakilin = the representative
ya = he
- a completed-action marker

This pattern is standard. Hausa usually keeps that subject marker even when the subject noun is already stated.

What exactly does ya mean here?

Ya is the 3rd person singular masculine subject marker used in the completive/perfective form. In simple terms, it often corresponds to English he did, he has done, or just a simple past translation depending on context.

So ya samar can mean something like:

he provided
he produced
he has provided
