Puffed up Dublin parliamentarian adopts superior note (5)
I believe the answer is:
tumid
'puffed' is the definition.
(synonyms)
'up dublin parliamentarian adopts superior note' is the wordplay.
'up dublin parliamentarian' becomes 'td' (I am not sure about this - if you are sure you should believe this answer much more).
'adopts' means one lot of letters goes inside another.
'superior' becomes 'u' (I've seen this in other clues).
'note' becomes 'mi' (as in 'do re mi').
'u'+'mi'='umi'
'td' going around 'umi' is 'TUMID'.
Can you help me to learn more?
(Other definitions for tumid that I've seen before include "Abnormally swollen" , "Bulging" , "Bloated" .)
