Agreeing entirely with Finnish university about new article in retrospect (9)
I believe the answer is:
unanimous
'agreeing entirely' is the definition.
'unanimous' can be an answer for 'agreeing' (thesaurus). I am not sure about the 'entirely' bit.
'finnish university about new article in retrospect' is the wordplay.
'finnish' becomes 'Suomi' (synonyms).
'university' becomes 'U' (abbreviation for university).
'about' means one lot of letters goes inside another.
'new article' becomes 'nan' (I can't explain this - if you can you should believe this answer much more).
'in retrospect' says the letters should be written in reverse (in retrospect means looking back).
'suomi'+'u'='suomiu'
'suomiu' going around 'nan' is 'suominanu'.
'suominanu' written backwards gives 'UNANIMOUS'.
'with' is the link.
Can you help me to learn more?
(Other definitions for unanimous that I've seen before include "Concerted" , "Acting together" , "All in agreement, no exceptions" , "without dissent" , "With one mind" .)
