'antiquated' is the definition.
(thesaurus)

'fuddy-duddy it one even essentially follows' is the wordplay.
'fuddy-duddy' becomes 'prim' (I can't justify this - if you can you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'essentially' means to look at the middle letters.
'follows' says to put letters next to each other.
The centre of 'even' is 've'.
'prim'+'it'+'i'+'ve'='PRIMITIVE'
