In Ireland, it can bring unrest to central Germany (7)
I believe the answer is:
munster
'in ireland it can' is the definition.
I can't tell whether this definition defines the answer.
'unrest to central germany' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'unrest' is 'unster' which is located in the answer.
A single letter 'm' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'bring' acts as a link.
Can you help me to learn more?
(Other definitions for munster that I've seen before include "Turns me into a province" , "Irish province or German city" , "European city" , "Irish quarter?" , "Province of Ireland" .)
