To make similar or to assimilate; an archaic or variant form of 'assimilate.'
A rare variant of 'assimilate,' possibly influenced by forms found in Middle French and Medieval Latin. The '-ulate' ending suggests diminutive or iterative meaning (doing something repeatedly or to a lesser degree), though this usage is now obsolete.
This word is a ghost in English—almost never used anymore—but it shows how languages constantly prune their vocabulary, keeping only the most useful forms and letting variants fade away like unused tools.
