Toy's success with daughter followed by grind (8)
I believe the answer is:
windmill
'toy's' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'success with daughter followed by grind' is the wordplay.
'success' becomes 'win' (I've seen this in another clue).
'with' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'followed by' says to put letters next to each other.
'grind' becomes 'mill' (synonyms).
'win'+'d'+'mill'='WINDMILL'
Can you help me to learn more?
(Other definitions for windmill that I've seen before include "It would stir Quixote to action" , "Child's toy; air-powered generator" , "Power generator with sails" , "Machine worked by turning vanes" , "Air-driven device" .)
