For Louis I, I'm not sure this shows contempt (4)
I believe the answer is:
jeer
'shows contempt' is the definition.
'jeer' can be an answer for 'contempt' (thesaurus). I'm not certain of the 'shows' bit.
'for louis i i'm not sure' is the wordplay.
'for louis i' becomes 'je' ('I' in French - Louis is a common French name).
'i'm not sure' becomes 'er' (expression of hesitation).
'je'+'er'='JEER'
'this' is the link.
Can you help me to learn more?
(Other definitions for jeer that I've seen before include "Rudely mocking remark" , "Mock rudely" , "Mock - laugh at" , "Henry ---, Richard II's enemy, successor" , "Ridicule noisily" .)
