In Kildare, non-drinker empties large container for boiling water (6)
I believe the answer is:
kettle
'container for boiling water' is the definition.
(I've seen this before)
'in kildare non-drinker empties large' is the wordplay.
'in kildare' becomes 'ke' (I can't justify this - if you can you should give a lot more credence to this answer).
'non drinker' becomes 'tt' (abbreviation for teetotaller).
'empties' means to remove the middle letters (I've seen 'emptied' mean this).
'large' with its centre removed is 'le'.
'ke'+'tt'+'le'='KETTLE'
Can you help me to learn more?
(Other definitions for kettle that I've seen before include "Check elements causing trouble in demonstration" , "Container for heating 10" , "Drum and metal pot" , "Kitchen boiler?" , "Container for boiling water" .)
