I believe the answer is:

underground

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

'resistance' is the definition.
(I know that resistance can be written as underground)

'insufficiently worn down?' is the wordplay.
'insufficiently' becomes 'under' (I can't explain this - if you can you should believe this answer much more).
'worn down?' becomes 'ground' (ground down).
'under'+'ground'='UNDERGROUND'

Can you help me to learn more?

(Other definitions for underground that I've seen before include "Secret resistance movement" , "In hiding" , "Tube; covert" , "Hidden away" , "Travel on this" .)

I've seen this clue in The Independent.
