Satisfy nation without time (4)
I believe the answer is:
sate
'satisfy' is the definition.
(I've seen this in another clue)
'nation without time' is the wordplay.
'nation' becomes 'sae' (I can't justify this - if you can you should give a lot more credence to this answer).
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'time' becomes 't' (abbreviation).
'sae' placed around 't' is 'SATE'.
Can you help me to learn more?
(Other definitions for sate that I've seen before include "Satisfy completely" , "Satisfy to the full" , "Satisfy - surfeit" , "Provide with more than enough" , "replete" .)
