Uniform put on group who serve hot drink in this (3)
I believe the answer is:
urn
'uniform put on group who serve hot drink in this' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'uniform put on group who serve' is the wordplay.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'put on group who serve' becomes 'rn' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'u'+'rn'='URN'
Can you help me to learn more?
(Other definitions for urn that I've seen before include "Tea vessel or ash container" , "Large vase for holding ashes of dead person" , "Funerary vessel" , "Samovar, perhaps" , "Burial vase" .)
