In Ireland, time for love (4)
I believe the answer is:
mayo
'in ireland' is the definition.
The definition suggests a singular noun which matches the answer.
'time for love' is the wordplay.
'time' becomes 'may' (I've seen this before).
'for' says to put letters next to each other.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'may'+'o'='MAYO'
Can you help me to learn more?
(Other definitions for mayo that I've seen before include "Ir. county; salad dressing" , "Saucy thing" , "Eg, Braeburn or Cox" , "You'll find it in the Emerald Isle" , "Salad dressing (informal)" .)
