Don't stop persons at sea (5,2)
I believe the answer is:
press on
'don't stop' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'persons at sea' is the wordplay.
'at sea' is an anagram indicator.
'persons' anagrammed gives 'PRESS ON'.
Can you help me to learn more?
(Other definitions for press on that I've seen before include "Persevere doggedly, quickly" , "Continue going forward" , "don't stop!" , "Hasten insistently" , "Continue (regardless)" .)
