Worry about class with fool lacking distinction (5)
I believe the answer is:
eclat
'fool lacking distinction' is the definition.
'eclat' can be an answer for 'distinction' (I've seen this before). I'm unsure of the 'fool lacking' bit.
'worry about class' is the wordplay.
'worry' becomes 'eat' (something worrying may eat someone up).
'about' means one lot of letters goes inside another.
'class' becomes 'cl' (I've seen this in other clues).
'eat' enclosing 'cl' is 'ECLAT'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for eclat that I've seen before include "Brilliance" , "Splash" , "Enthusiastic approval" , "Brilliant display or effect" , "Distinguished success" .)
