Negligible little Malcolm (7)

I believe the answer is:

minimal

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

'negligible' is the definition.
(similar in meaning)

'little malcolm' is the wordplay.
'little' becomes 'mini'.
'malcolm' becomes 'mal' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mini'+'mal'='MINIMAL'

Can you help me to learn more?

(Other definitions for minimal that I've seen before include "Very little" , "Of a smallest amount" , "Token" , "Very small, the least possible (7)" , "barely worth considering" .)

I've seen this clue in the Evening Standard.
