Villager won’t take profession?

So basically i got one villager in my base. I brought him from a breeder. I give him a lectern and a bed, even a door, but he’s not picking the profession. I tried giving him a different profession, but he still doesn’t take the profession. What do I do?

Is it a normal villager or a nitwit?

Wait, are there nitwits after 1.11? I mean he came from the breeder just like all of the others. When i right click him nothing happens. He doesn’t do the nod.

I don’t know but they can bred. Make a new house and hope for the best.
