Wild dream about Irish lover (7)
I believe the answer is:
admirer
'lover' is the definition.
(admirer is a kind of lover)
'wild dream about irish' is the wordplay.
'wild' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'irish' becomes 'ir' (abbreviation).
'dream' is an anagram of 'admer'.
'admer' placed around 'ir' is 'ADMIRER'.
(Other definitions for admirer that I've seen before include "Married to suitor" , "Married to one who thinks highly of" , "One who regards (someone) with respect" , "Married to one who cherishes" , "sweetheart" .)
