Very hot and bothered at last (3)
I believe the answer is:
red
This clue might be a double definition.
'very hot' is the first definition.
'red' can be an answer for 'hot' (thesaurus). I am not sure about the 'very' bit.
'bothered at last' is the second definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I can't see?
'and' acts as a link.
Can you help me to learn more?
(Other definitions for red that I've seen before include "Scarlet or vermilion" , "Very angry, seeing this" , "Colour of communism" , "Colour of blood" , "Crimson" .)
