Jaguar after run to enter again (6)
I believe the answer is:
retype
'jaguar after run' is the definition.
I can't tell whether this defines the answer.
'enter again' is the wordplay.
I cannot really see how this works, but
'enter' could be 'type' (I've seen this in another clue) and 'type' is found in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for retype that I've seen before include "Produce document again" , "impress again" , "Repeat work in pool" , "Produce amended" , "Tap out again on keyboard" .)
