Set out with a warm-hearted bright fellow (5)
I believe the answer is:
array
'set out' is the definition.
(synonyms)
'with a warm-hearted bright fellow' is the wordplay.
'with' is a charade indicator (letters next to each other).
'hearted' means to look at the middle letters.
'bright fellow' becomes 'ray' (man's name. I am not sure about the 'bright' bit.).
The central letters of 'warm' are 'ar'.
'ar' next to 'ray' is 'ARRAY'.
Can you help me to learn more?
(Other definitions for array that I've seen before include "Rich clothing" , "Ordered arrangement (of troops)" , "Impressive display; matrix" , "Marshal" , "An imposing series or display" .)
