One employed to measure up The Queen? (5)
I believe the answer is:
ruler
'the queen?' is the definition.
(I've seen this in another clue)
'one employed to measure up' is the wordplay.
I cannot quite see how this works, but
'measure' could be 'rule' (rule is a kind of measure) and 'rule' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ruler that I've seen before include "Maharaja, e.g." , "One measures" , "Eg, king, emperor" , "Strip with straight edges" , "Head of state" .)
