From Middle English -yf, from Anglo-Norman -if (feminine -ive), 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.
- An adjective suffix signifying relating or belonging to, of the nature of, tending to, or serving to; as: affirmative, active, conclusive, corrective, diminutive.
adjectival suffix: of the nature of; tending to
