Caught entering the store, you truss up and take to (6)
I believe the answer is:
escort
'take to' 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?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for escort that I've seen before include "Ford car, first produced in 1968" , "One who accompanies, for protection or as an honour" , "restraint" , "Custodian" , "Accompany - Ford model" .)
