Cause of a flutter in the office? (9,4)
I believe the answer is:
secretary bird
'flutter in the office?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'cause of a' is the wordplay.
I cannot really see how this works, but
'cause' could be 'secretary' (secretary is a kind of cause) and 'secretary' is found within the answer.
The remaining letters 'bird' is a valid word 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 secretary bird that I've seen before include "Long-legged snake-eating raptor" , "flighty type" , "African snake eater" , "Flyer" .)
