Irish rise: plebs’re somehow immune to subjugation (13)

I believe the answer is:

irrepressible

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

'immune to subjugation' is the definition.
I can't judge whether this defines the answer.

'irish rise plebs're somehow' is the wordplay.
'irish' becomes 'IR' (abbreviation).
'somehow' indicates anagramming the letters.
'rise'+'plebsre'='riseplebsre'
'riseplebsre' with letters rearranged gives 'repressible'.
'ir'+'repressible'='IRREPRESSIBLE'

Can you help me to learn more?

(Other definitions for irrepressible that I've seen before include "Uninhibited" , "Unable to be restrained" , "Not willing to be restrained" , "Bubbly" , "Boisterous" .)
