gosport

I'm a little stuck... Click here to teach me more about this clue!

'for hampshire town' is the definition.
(Gosport is a town in Hampshire)

I don't understand how the rest of the clue works.

(Other definitions for gosport that I've seen before include "Facing Pompey" , "Hampshire coastal town" , "Hants town" .)

I've seen this clue in The Independent.
