Temperature in Granada bothered knight, a dashing blade (9)
I believe the answer is:
dartagnan
'a dashing blade' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'temperature in granada bothered knight' is the wordplay.
I cannot really see how this works, but
'temperature' could be 't' (abbreviation) and 't' is present in the answer.
an anagram of 'granada' is 'daragna' which is within the left over letters.
'knight' could be 'n' (chess abbreviation) and 'n' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dartagnan that I've seen before include "Hero of Les Trois Mousquetaires (Dumas)" , "Novel hero" , "Hero of The Three Musketeers" , "Front of advancing army" , "French hero ..." .)
