Might have small capabilities (6)
I believe the answer is:
powers
'capabilities' is the definition.
The answer and definition can be both human attributes as well as being plural nouns.
Maybe there's an association between them I don't understand?
'might have small' is the wordplay.
'might' becomes 'power' (being mighty).
'have' is a charade indicator (letters next to each other).
'small' becomes 's' (abbreviation - e.g. clothes size).
'power'+'s'='POWERS'
Can you help me to learn more?
(Other definitions for powers that I've seen before include "Countries in terms of their world influence" , "Supplies with energy" , "The ...... that be are people in authority" .)
