Be inconsistent, with indignant cry interrupting informal greeting (2-2)
I believe the answer is:
yo-yo
'be inconsistent with indignant cry' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'interrupting informal greeting' is the wordplay.
I cannot really see how this works, but
'greeting' could be 'yo' and 'yo' is located in the answer.
The remaining letters 'yo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for yo-yo that I've seen before include "Toy consisting of a reel and string" , "Fluctuate rapidly" , "Child's toy on a string" , "Toy consisting of a spool and string" , "Reel-and-string toy" .)
