Crossword Genius

Popular group, with leader away, failing to perform (8)

Ross

I believe the answer is:

inaction

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

'failing to perform' is the definition.
I can't judge whether this definition defines the answer.

'popular group with leader away' is the wordplay.
'popular' becomes 'in' (something that's 'in' is fashionable).
'group' becomes 'faction'.
'with leader away' means to remove the first letter.
'faction' with its first letter removed is 'action'.
'in'+'action'='INACTION'

Can you help me to learn more?

(Other definitions for inaction that I've seen before include "Stasis" , "Failure to exert oneself" , "lack of engagement" , "This is not working" , "Dormancy" .)
