Specifying which container, we get right to the point (4)
I believe the answer is:
ewer
'specifying which container' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'we get right to the point' is the wordplay.
'get right' becomes 'r' (I've seen this in other clues).
'to' says to put letters next to each other (I've seen this in other clues).
'the point' becomes 'e' (compass point).
'we'+'r'='wer'
'wer' after 'e' is 'EWER'.
Can you help me to learn more?
(Other definitions for ewer that I've seen before include "A wide-mouthed water-jug" , "Were (anag)" , "Jar for water" , "Decorative pitcher" , "Large pitcher" .)
