One half of Ireland consumed by short witty remark with bawdy ending (6)
I believe the answer is:
moiety
'one half' is the definition.
(moiety is a kind of half)
'ireland consumed by short witty remark with bawdy ending' is the wordplay.
'ireland' becomes 'ie' (two letter country code).
'consumed by' means one lot of letters goes inside another.
'short' means to remove the last letter.
'witty remark' becomes 'mot' (I've seen this in another clue).
'with bawdy ending' becomes 'ty' (I can't justify this - if you can you should give a lot more credence to this answer).
'mot' with its final letter removed is 'mo'.
'mo'+'ty'='moty'
'ie' put within 'moty' is 'MOIETY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for moiety that I've seen before include "Fair portion" , "One of two equal parts" , "Oy! Time for a half" , "Part" , "Either of two" .)
