Some cross a moat in Pago Pago locale (5)
I believe the answer is:
samoa
'pago pago locale' is the definition.
(I've seen this in another clue)
'some cross a moat' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SAMOA' is hidden within 'cross a moat'.
'in' acts as a link.
(Other definitions for samoa that I've seen before include "Southwest Pacific island group" , "South Pacific island country, gaining its independence from New Zealand in 1962" , "Group of islands in the South Pacific" , "South-west Pacific nation" , "Pacific island nation, capital Apia" .)
