Talk of going ashore? (3)
I believe the answer is:
gas
'talk' is the definition.
(thesaurus)
'of going ashore?' is the wordplay.
'of' indicates a hidden word.
'GAS' is hidden within 'going ashore'.
(Other definitions for gas that I've seen before include "Piped fuel" , "chew the fat" , "Domestic fuel" , "Fuel; idle talk" , "See 2" .)
