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 there's a link between them I don't understand?
'persons at sea' is the wordplay.
'at sea' is an anagram indicator.
'persons' with letters rearranged 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)" .)
