Odd characters leaving Georgian poet's country (4)

I believe the answer is:

erin

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

'poet's country' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for erin that I've seen before include "Early and poetic name here" , "Old Ireland" , "country" , "Let ... Remember (song)" , "Literary term for Ireland" .)

I've seen this clue in The Sun.
