A Great Sealer

[petland]

I've asked before but any more suggestions for a town or city described as "a great sealer"?

[Captain2]

Do we know how many letters in the answer?

[petland]

Number of letters not known - it's just a cryptic clue

Cork?

[petland]

Thanks. Cork seems to be favourite although can't see the "great" significance

Wax? It used to be used to seal letters.
And to wax is to get bigger

[elliemay1]

Has to be a town or city, sandy

Don't know if it is relevant bt the Queen is the holder of The Great Seal

W(h)ales ?

[sandyRoe]

I need to carefully read the question.

Sizewell ?

[Canary42]

.... as in sealing before painting :-

size (noun)
A gelatinous solution used in ... preparing plastered walls for decoration.

[petland]

Thanks for your suggestions. Here's my own interpretation - Exeter
Exe short for excellent (great), ter sounds like tar (sealer) ??

I think you may be over complicating things.

Good luck with whatever you decide on.
