A cat in charge at a very small level (6)
I believe the answer is:
atomic
'small level' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'a cat in charge at a' is the wordplay.
'a cat' becomes 'tom' (a tom is a male cat).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'at' says to put letters next to each other (I've seen this in other clues).
'tom'+'ic'='tomic'
'tomic' put after 'a' is 'ATOMIC'.
'very' acts as a link.
Can you help me to learn more?
(Other definitions for atomic that I've seen before include "Basically simple" , "Realting to nuclear energy" , "Extremely minute" , "Like some clocks" , "Based on nuclear energy" .)
