This document summarizes the history of adjectives in the English language from Old English to Modern English. It discusses how adjectives declined in Old English based on gender, number, and case. By Middle English, adjectives lost declension and gender. In Early Modern English, suppletive adjectives like 'good' and 'bad' took on their modern forms, and analytical comparison was introduced for multisyllabic adjectives. Modern English now has two methods of comparison: synthetic for short adjectives and analytical for longer ones.
