Made an effort, seeing queen in range (6)
I believe the answer is:
'made an effort' is the definition.
(I've seen this in another clue)
'queen in range' is the wordplay.
I cannot really understand how this works, but
'queen' could be 'r' (abbreviation for regina, e.g. in ER ) and 'r' is found in the answer.
'range' could be 'stove' (synonyms) and 'stove' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'seeing' is the link.
Can you help me to learn more?
(Other definitions for strove that I've seen before include "Made great efforts" , "Endeavoured" , "Voters (anag) - made every effort" , "Struggled" , "Tried hard for voters" .)
