Teaching aids for flying certificate after drink (5,5)
I believe the answer is:
water wings
'teaching aids' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'flying certificate after drink' is the wordplay.
'flying certificate' becomes 'wings' (I can't justify this - if you can you should believe this answer much more).
'after' means one lot of letters go next to another.
'drink' becomes 'water' (water is an example).
'wings' put after 'water' is 'WATER-WINGS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for water wings that I've seen before include "Support for one learning to swim" , "Floats for swimmer" .)
