Vagrant longed to tour a county of Ireland (7)
I believe the answer is:
donegal
'county of ireland' is the definition.
'Donegal' can be an answer for 'county' (county of Ireland). I am unsure of the 'of ireland' bit.
'vagrant longed to tour a' is the wordplay.
'vagrant' is an anagram indicator (I've seen this in other clues).
'to tour' is an insertion indicator (to tour can mean to go around).
'longed' is an anagram of 'donegl'.
'donegl' placed around 'a' is 'DONEGAL'.
Can you help me to learn more?
(Other definitions for donegal that I've seen before include "Ireland's northmost county" , "County of NW?Ireland" , "County of NW Ireland" , "Irish town" , "Northernmost Irish county" .)
