Undistinguished little men (6)

I believe the answer is:

normal

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

'men' is the definition.
Although both the answer and definition are nouns, they are not in the same form of the noun.

'undistinguished little' is the wordplay.
'undistinguished' becomes 'norma' (I can't justify this - if you can you should believe this answer much more).
'little' becomes 'l' (abbreviation for little).
'norma'+'l'='NORMAL'

Can you help me to learn more?

(Other definitions for normal that I've seen before include "Unexceptional" , "Ordinary, usual" , "Customary" , "Regular" , "Ordinary, not extraordinary" .)

I've seen this clue in the Evening Standard.
