companionable

the word "companionable" is a relatively modern english formation, built upon the older noun "companion." this noun itself originates from the late latin companionem, literally meaning "one who breaks bread with another," derived from com- (with) and panis (bread). the suffix "-able," of latin origin, was later appended to create an adjective describing the quality of being fit for or inclined to be a good companion. thus, the literal sense of "capable of being a bread-sharer" evolved into the modern abstract meaning of being sociable, friendly, and pleasant company.

Structure: companion + able companion: from latin companionem (one who eats bread with another), via old french compaignon. functions as the core noun root meaning "associate" or "partner". able: from latin -abilis, a suffix forming adjectives meaning "capable of, fit for, tending to". functions as an adjective-forming suffix.
