Crazier to plunge over jetty (7)
I believe the answer is:
dippier
'crazier' is the definition.
Both the answer and definition are comparative adjectives.
Perhaps they are linked in a way I don't understand?
'plunge over jetty' is the wordplay.
'plunge' becomes 'dip' (synonyms).
'over' means one lot of letters go next to another.
'jetty' becomes 'pier' (I've seen this before).
'dip'+'pier'='DIPPIER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for dippier that I've seen before include "Relatively crazy" , "comparatively silly" .)
