The topic of the convo was centred AROUND / ON dress designs that she wanted. which is grammatically better?

Question

Is AROUND or ON, grammatically better in the sentence? i thought around was better.. .but my friend says on.

Answer 1

around in my opinion

Answer 2

TRo me On seems the better choice but I can not say why

Answer 3

it's on.  Something that is centered (in the middle) can't also go around (revolve)

Answer 4

On, i.e. to be "on topic".

Answer 5

Convo - did nobody tell you that is not a real word? It's "converstation". The word you need, in this instance, is "around". The whole sentence does sound slightly awkward however. Try a different construction, something like: "The central topic of the conversation was her desire for dress designs."
