Go on, lad. Push out the boat (7)
I believe the answer is:
gondola
'boat' is the definition.
(gondola is a kind of boat)
'go on lad push out the' is the wordplay.
'go on lad' can be anagrammed to 'GONDOLA'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for gondola that I've seen before include "Palmieris' craft" , "mountain climber" , "Goon lad (anag.)" , "Cabin suspended from an airship" , "Compartment suspended from an airship" .)
