Irregular poems tie into typical models (8)
I believe the answer is:
epitomes
'typical models' is the definition.
'epitomes' can be an answer for 'models' (epitome is a kind of model). I am not sure about the 'typical' bit.
'irregular poems tie' is the wordplay.
'irregular' is an anagram indicator.
'poems'+'tie'='poemstie'
'poemstie' anagrammed gives 'EPITOMES'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for epitomes that I've seen before include "Standards or typical examples" , "Perfect examples" .)
