Really enjoying tour of Irish glen (9)
I believe the answer is:
relishing
'really enjoying' is the definition.
'relishing' can be an answer for 'enjoying' ('relish' can be a synonym of 'enjoy'). I am not sure about the 'really' bit.
'tour of irish glen' is the wordplay.
'tour of' is an anagram indicator (I've seen 'touring' mean this (touring can mean moving around)).
'irish'+'glen'='irishglen'
'irishglen' anagrammed gives 'RELISHING'.
Can you help me to learn more?
(Another definition for relishing that I've seen is " Greatly enjoying".)
