It is given but not away (7)
I believe the answer is:
present
'it is given' is the definition.
(I've seen this before)
'not away' is the wordplay.
I cannot really see how this works, but
'not' could be 'nt' (synonyms) and 'nt' is found within the answer.
The remaining letters 'prese' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'but' acts as a link.
Can you help me to learn more?
(Other definitions for present that I've seen before include "Current" , "Introduce formally" , "in a particular place" , "Hand over < donation" , "offering" .)
