An archaic or obsolete adjective meaning easy or accommodating, formed with an old suffix.
From Middle English 'ese' or 'ees' (easy) plus the suffix -some. This construction is no longer productive in modern English, having been replaced by 'easy' as the standard adjective.
Words like eesome, fearsome, and gladsome show how English once built adjectives differently—we loved adding -some to create vivid descriptions, but we gradually shifted to shorter forms!
