Like diamonds, suitably? (3)
I believe the answer is:
red
'like diamonds suitably?' is the definition.
I can't judge whether this definition defines the answer.
'like diamonds' is the wordplay.
'like' becomes 're' (I can't justify this - if you can you should give a lot more credence to this answer).
'diamonds' becomes 'd' (abbreviation in bridge say).
're'+'d'='RED'
Can you help me to learn more?
(Other definitions for red that I've seen before include "Primary colour" , "14 -- breed of 4" , "Colour of communism" , "Very angry, seeing this" , "Bloodshot" .)
