Meaning of 'Back is a verb'

Dear teachers,

Please read:

We told her we’[color=red]d [color=green]back her [color=darkblue]whatever.

1/"'d" = would (past form of “will”)
Is it right?

2/Back is a verb. It means…

3/ Whatever means…

Please help me. I can’t find the meaning in the dictionary.


With no further context, that’s the best I can do.

Many thanks, teacher.

Could you explain me what does “no matter what” mean?
It means in any way, at any conditions, we will support her?


Yes, that’s basically right.
No matter what (happens)” means “it doesn’t matter what happens or what the situation is. Anything that happens will be accepted.”
