Dashing fellow unusually bold about love (5)
I believe the answer is:
blood
'dashing fellow' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'unusually bold about love' is the wordplay.
'unusually' indicates an anagram.
'about' means one lot of letters goes inside another.
'love' becomes 'o' (love means zero in tennis).
'bold' is an anagram of 'blod'.
'blod' going around 'o' is 'BLOOD'.
Can you help me to learn more?
(Other definitions for blood that I've seen before include "Fluid in veins" , "Become the duty of" , "Male siblings -- sworn friends" , "Oxygen carrier" , "Vein filler" .)
