It’s rational to take time off and empower (6)
I believe the answer is:
enable
'empower' is the definition.
(I've seen this before)
'it's rational to take time off and' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'rational' becomes 'able' (I can't justify this - if you can you should give a lot more credence to this answer).
'to take' means one lot of letters goes inside another.
'time' becomes 'ad'.
'off' suggests deleting specific letters.
'and' with 'ad' taken out is 'n'.
'e'+'able'='eable'
'eable' placed around 'n' is 'ENABLE'.
Can you help me to learn more?
(Other definitions for enable that I've seen before include "Allow" , "Make possible using baleen" , "Permit or facilitate" , "Make it possible for someone to do something" , "Facilitate or make possible" .)
