-ive

From Middle English -yf, from Anglo-Norman -if from Latin -īvus. Until the fourteenth century, all Middle English loanwords from Anglo-Norman ended in -if (compare actif, natif, sensitif, pensif etc.). Under the influence of literary Neo-Latin, both languages introduced the form -ive. Those forms that have not been replaced were subsequently changed to end in -y (compare hasty, from hastif, jolly, from jolif etc.).

Like the Latin suffix -iō (genitive -iōnis), the Latin suffix -ivus is appended to the perfect passive participle to form an adjective of action.
