Point to the jug that's more modern (5)
I believe the answer is:
newer
'more modern' is the definition.
('new' is associated in meaning with 'modern')
'point to the jug' is the wordplay.
'point' becomes 'n' (North).
'to the jug' becomes 'ewer' (type of vessel).
'n'+'ewer'='NEWER'
'that's' is the link.
(Other definitions for newer that I've seen before include "More up-to-date" , "Fresher or more novel" , "More pristine or recently invented" , "More current" , "More modern" .)
