Omitting outré watercolour somehow supposed to represent place in Ireland (6)
I believe the answer is:
carlow
'supposed to represent place in ireland' is the definition.
I can't tell whether this definition defines the answer.
'omitting outre watercolour somehow' is the wordplay.
'omitting' suggests deleting specific letters.
'somehow' is an anagram indicator.
'watercolour' with 'outre' taken away is 'waclor'.
'waclor' with letters rearranged gives 'CARLOW'.
Can you help me to learn more?
(Another definition for carlow that I've seen is " Irish county".)
