Small and delicate — so? (6)
I believe the answer is:
slight
'so?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'small and delicate' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'and' says to put letters next to each other.
'delicate' becomes 'light' (similar in meaning).
's'+'light'='SLIGHT'
Can you help me to learn more?
(Other definitions for slight that I've seen before include "Slender; rebuff" , "Minor -- snub" , "Minor - offence" , "Deliberately discourteous act" , "Deliberate discourteous act" .)
