How to make neat see-saw or yo-yo? (9)
I believe the answer is:
alternate
'see-saw or yo-yo?' is the definition.
I can't judge whether this definition defines the answer.
'how to make neat' is the wordplay.
'how' becomes 'alter' (I can't explain this - if you can you should give a lot more credence to this answer).
'to make' indicates an anagram.
'neat' anagrammed gives 'nate'.
'alter'+'nate'='ALTERNATE'
Can you help me to learn more?
(Other definitions for alternate that I've seen before include "Interchange" , "Change repeatedly between two" , "Every second one of a series" , "go back and forth" , "In turns, first one then the other" .)
