“Their names are both Trevor” would sound the most unambiguous to me.
The trevors are named trevor.
Their names are Roberts Paulsons
Them be Trevors
This is the one grammatically acceptable time to use Thar
Both correct, it depends whether you are saying,1 “They both have names and their names are Trevor” or “They both have the same name and that name is Trevor”.
So the real question is are you talking about their shared name or both of their names separately?
I would just say “They’re both named Trevor.”
What if there’s more than two Trevors?
They’re all named Trevor.
Both of their names is Trevor?
Trevor’re their names.
My interpretation: “their name is Trevor” is grammatically correct, but semantically means their collective name is Trevor, not that they’re both called Trevor.
“Their names are Trevor” is incomplete because the subject implies a plural while the object is singular. This could work if you were to list multiple names: “their names are Trevor and Trevor.”
“They’re both named Trevor.”
They’re named Trevor.
Both don’t sound right as they are ambiguous. “Their name is Trevor,” sounds like it is talking about a single person. “Their names are Trevor” feels incomplete. “They are both named Trevor” or “Their names are Trevor and Trevor” solves that ambiguity.
Their names is Trevor
We are all Trevor
On this blessed day
Speak for yourself
I am all Trevor
Both their names are Trevor
When would you use both their vs both of their in this scenario? Your’s makes sense but I would have put an of, and I’m wondering if it’s just a waste of letters.
Both are valid. One might be more likely to feel more natural to say depending on where that person is from or how they were taught, that’s it.
These are our Trevors.
“Their names are Trevor.”
You could use some Irish English, then you could be saying “Themmuns are called Trevor” that way there’s zero ambiguity
