Where, in Ireland, love comes to blossom (4)
I believe the answer is:
mayo
'where in ireland' is the definition.
The definition suggests a singular noun which matches the answer.
'love comes to blossom' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'comes to' means one lot of letters go next to another.
'blossom' becomes 'may' (I've seen this before).
'o' put after 'may' is 'MAYO'.
Can you help me to learn more?
(Other definitions for mayo that I've seen before include "Thick creamy dressing" , "You'll find it in the Emerald Isle" , "Saucy thing" , "part of Ireland" , "radio presenter" .)
