Annoying enough to make Kim sore (7)

I believe the answer is:

irksome

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

'annoying enough' is the definition.
'irksome' can be an answer for 'annoying' (I've seen this before). I'm unsure of the 'enough' bit.

'make kim sore' is the wordplay.
'make' indicates anagramming the letters.
'kim'+'sore'='kimsore'
'kimsore' anagrammed gives 'IRKSOME'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for irksome that I've seen before include "Smoker I find annoying" , "'Annoying, irritating or boring (7)'" , "Tiresome, irritating" , "Bothersome, annoying" , "Smokier (anag.)" .)

I've seen this clue in The Irish Independent.
