'A group of mums IS campaigning...' or 'A group of mums ARE campaigning...'?

[Spidermama]

I think it's 'is' but it sounds wrong.

'A group is campaigning' is right.

so therefore 'a group (of mums) is campaigning' is still right.

shoving in a few extras like (of mums) doesn't alter the sentence structure.

why is that pompous btw? she said pompously

A group is

Mums are

We are primarily talking about A Group. Therefore it is. Not are. Do you see?

If it helps, it would be singular in the other three languages I could say it in.

Custy Its because (I think)..

They are really saying

"a group is campaigning"

the fact that they are mums is an add in and not relevant to the grammar of it.

a group of fish is campigning
a group of nuns is campainign
a group of truckers is campaigning

So a group is a single thing. mums/nuns/fish/truckers are not.

ooops to weird campaigning spellings

so A group is a singular even though the group is plural

therefore it is an is?

Nickelback is playing Rockstars with Englebert Humperdink?

No, the group isnt plural.

There is only one group

The definition of group is irrelevant to the case.

It would be plural if it was "There are groups of mums campaigning"

So, in terms of language alone, the subject is the 'group' and not the 'mums'.

are - because it's a group of mums so more than one.

no cornsilk, it's only ONE group of mums. There might be more than one mum in it, but it's ONE GROUP, not many groups.

A GROUP OF MUMS IS
GROUPS OF MUMS ARE

Might help to think that the of mums is an aside

You wouldn't say:
"A group are being set up in the village for mums".

Pedantry squared - why not "A group of mothers...." Or "parents"

I'll get my coat.........

Because there is only one group of mums, Custardo. Therefore it's singular. A group is, two groups are. In this case the mums are defined by their membership of the group.

righto i see thank you

doesn't sound right though
