There's less in a jug at the welfare centre (5)
I believe the answer is:
fewer
'there's less' is the definition.
I can't tell whether this defines the answer.
'jug at the welfare centre' is the wordplay.
'jug' becomes 'ewer' (type of vessel).
'at' means one lot of letters go next to another (I've seen this in other clues).
'centre' means to look at the middle letters.
The middle of 'welfare' is 'f'.
'ewer' put after 'f' is 'FEWER'.
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for fewer that I've seen before include "in smaller numbers" , "Less in number" , "smaller number of people" , "Reduced" , "Not so many" .)
