Good question. Was thinking the same thing. But I think this is the verb which uses ho/ha etc. Avere. So would be loro hanno
What does hanno mean?
It is the 3rd person plural of the verb avere. click on the verb in the sentence and check the conjugation of avere or of any verb
To have is not the same as to own. Ownership the a legal construct of possession. You can have a house, a boyfriend, an opinion, a plan, a job without owning these. You can have a shirt (by borrowing, or picking it up but not buying it), without owning it.
