Sheepish type Maureen tours Ireland (6)
I believe the answer is:
merino
'sheepish type' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'maureen tours ireland' is the wordplay.
'maureen' becomes 'Mo' (short for Maureen).
'tours' is an insertion indicator (to tour can mean to go around).
'ireland' becomes 'erin' (poetic name for Ireland).
'mo' enclosing 'erin' is 'MERINO'.
Can you help me to learn more?
(Other definitions for merino that I've seen before include "Type of sheep" , "Sheep with fine quality fleece" , "The sheep provides fine wool" , "Long-haired sheep" , "Sheep from Spain with a heavy quality fleece" .)
