Where an Irishman can change his hat at half time (5)
I believe the answer is:
meath
'where an irishman' is the definition.
The definition suggests a singular noun which matches the answer.
'change his hat at half time' is the wordplay.
'change' indicates an anagram.
'hat' says to take the initial letters (I've seen 'hats' mean this (in a down clue, the letter at the top of the word)).
'half' indicates taking half.
The first letter of 'his' is 'h'.
'time' with half the letters taken is 'me'.
'h'+'at'+'me'='hatme'
'hatme' anagrammed gives 'MEATH'.
'can' acts as a link.
Can you help me to learn more?
(Other definitions for meath that I've seen before include "lost province" , "Tara's county" , "Irish county of ancient kings, site of Tara" , "part of Ireland" , "County NW of Dublin" .)
