"Carry On Jack" shown during holiday (7)
I believe the answer is:
restart
'carry' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'jack shown during holiday' is the wordplay.
'jack' becomes 'tar' (both are informal terms for sailor).
'shown during' means one lot of letters goes inside another.
'holiday' becomes 'rest' (rest can mean a holiday or break).
'tar' going into 'rest' is 'RESTART'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for restart that I've seen before include "launch again" , "Begin anew" , "Jumping the gun will mean" , "Commence again" , "begin afresh" .)
