Be greedy and thus outstrip? (8)
I believe the answer is:
overtake
'outstrip?' is the definition.
(thesaurus)
'be greedy and thus' is the wordplay.
I cannot really understand how this works, but
'be' could be 'take' (taking is a kind of being) and 'take' is found within the answer.
The remaining letters 'over' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for overtake that I've seen before include "possibly put behind one" , "Pass a car ahead" , "Catch unprepared" , "Leave behind" , "Travel past" .)
