Get off on anger in the country (7)
I believe the answer is:
ireland
'the country' is the definition.
(Ireland is a country)
'get off on anger' is the wordplay.
'get off' becomes 'land' (landing is a kind of getting. I am not sure about the 'off' bit.).
'on' means one lot of letters go next to another.
'anger' becomes 'ire' (ire is intense rage).
'land' after 'ire' is 'IRELAND'.
'in' is the link.
Can you help me to learn more?
(Other definitions for ireland that I've seen before include "Erin" , "An idler (anag)" , "Scorer" , "The Emerald Isle" , "Nation, the Oireachtas its parliament" .)
