Mollusc spurning new trip at sea (4)
I believe the answer is:
sail
'trip at sea' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'mollusc spurning new' is the wordplay.
'mollusc' becomes 'snail' (snail is a kind of mollusc).
'spurning' suggests deleting specific letters.
'new' becomes 'n' (abbreviation as in New Testament NT).
'snail' with 'n' removed is 'SAIL'.
Can you help me to learn more?
(Other definitions for sail that I've seen before include "Leave shore" , "Begin a voyage" , "Travel by ship" , "Fabric on a mast" , "Leave harbour" .)
