No female for gnat that circles planet? (7)
I believe the answer is:
orbiter
'circles planet?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'no female for gnat' is the wordplay.
'no' is a deletion indicator.
'female' becomes 'f' (common abbreviation).
'gnat' becomes 'biter' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' with 'f' taken out is 'or'.
'or'+'biter'='ORBITER'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for orbiter that I've seen before include "One goes round" , "Non-landing spacecraft" , "Satellite perhaps" , "Space vehicle" , "Circling spacecraft" .)
