What the Irish may be putting on or wearing (5)
I believe the answer is:
green
'wearing' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
'what the irish may be putting on' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' (regarding) and 're' is located in the answer.
The remaining letters 'gen' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for green that I've seen before include "conservationist" , "Fresh - environmentally friendly - colour" , "political activist" , "Caring for environment" , "Consultative document" .)
