Worst of anything I kept in home (10)

I believe the answer is:

naughtiest

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

'worst of anything i kept in home' is the definition.
I can't tell whether this defines the answer.

'anything i kept in home' is the wordplay.
'anything' becomes 'aught' ('aught' means anything).
'kept in' is an insertion indicator.
'home' becomes 'nest' (a bird's home).
'aught'+'i'='aughti'
'aughti' placed into 'nest' is 'NAUGHTIEST'.

Can you help me to learn more?

(Another definition for naughtiest that I've seen is " Most mischievous".)

I've seen this clue in The Times.
