Enter text again dealing with nature
I believe the answer is:
'enter text' is the definition.
I can't tell whether this defines the answer.
'again dealing with nature' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'dealing with' becomes 'ty' (I can't justify this - if you can you should believe this answer much more).
'nature' becomes 'P.E.' (P.E. is an example).
Can you help me to learn more?
(Other definitions for retype that I've seen before include "Put into printed characters again" , "Tap out again on keyboard" , "made to revise earlier draft perhaps" , "Produce document again" , "Produce amended" .)
