Note Clio, for example, departs, seeing the funny side (6)
I believe the answer is:
amused
'the funny side' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
'note clio for example departs' is the wordplay.
'note' becomes 'a' (musical note).
'clio for example' becomes 'muse' (Clio is the muse of history in Greek mythology).
'departs' becomes 'd' (abbreviation used in transport schedules).
'a'+'muse'+'d'='AMUSED'
'seeing' acts as a link.
Can you help me to learn more?
(Other definitions for amused that I've seen before include "Provoked mirth in" , "was entertaining" , "Victoria reputedly wasn't" , "Made (someone) laugh" , "Kept someone entertained" .)
