Assume ten love joining rather ingenious gentleman (3,7)
I believe the answer is:
don quixote
'ingenious gentleman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'assume ten love joining rather' is the wordplay.
'assume' becomes 'don' (I've seen this in another clue).
'ten' becomes 'X' (Roman numeral).
'love' becomes 'o' (love means zero in tennis).
'joining' indicates putting letters inside (inserted letters join the word).
'rather' becomes 'quite' (synonyms).
'x'+'o'='xo'
'xo' placed inside 'quite' is 'quixote'.
'don'+'quixote'='DON QUIXOTE'
Can you help me to learn more?
(Other definitions for don quixote that I've seen before include "Novel" , "book" , "chivalrous character" .)
