Don't stop persons going astray (5,2)
I believe the answer is:
press on
'don't stop' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'persons going astray' is the wordplay.
'going astray' indicates an anagram.
'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 "Continue (with action)" , "don't stop!" , "Continue going forward" , "Persevere doggedly, quickly" , "Keep going forward" .)
