Widget appropriate for hole in a hatch (7)
I believe the answer is:
adaptor
'widget' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'appropriate for hole in a hatch' is the wordplay.
I cannot really understand how this works, but
'appropriate' could be 'apt' (synonyms) and 'apt' is located in the answer.
'hole' could be 'o' and 'o' is found in the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for adaptor that I've seen before include "It enables fit" , "Kind of electric plug" , "Electrical connector" , "Connector for differing plug types" , "Electrical convertor" .)
