Might have small capabilities (6)

Ross

I believe the answer is:

powers

I'm a little stuck... Click here to teach me more about this clue!

'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" .)
