Going into mental meltdown here… which of these is correct?

It was one of those brilliantly sunny mornings that confuses the senses.

I think the second.

I'm with Frances, don't know the grammar, it just sounds better to me....

something to do with the morning being singular?

Yes, the second one sounds better to me too, but I think that’s because mornings is plural. But the subject of the sentence is one… so take the rest out and it becomes

it was one … that confuse the senses

So I suppose that, technically, it should be the first option (confuses) but it just doesn’t sound right.

Confused?

Yes, it's the second one. Get rid of 'one of' and it will be clear: those brilliant sunny mornings that confuse the senses. It is one of <i>those</i> and those are brilliantly sunny mornings....

formatting didn't work!

Frances, tc, Ani,

Many thanks. The second one it is, then.
