A "companionable" person is someone who (etymologically at least) is willing to share bread with you. "Companionable" is the adjective form of "companion," which ultimately derives from a combination of the Latin prefix com-, meaning "with" or "together," and the noun panis, meaning "bread, loaf, or food." "Companionable" first appeared in print in English in the 16th century (companion has been in use since the 14th). Other descendants of "panis" include "pantry" (a place for storing food), "pannier" (a basket such as might carry food), and "panettone" (a kind of yeast bread). Even "food" itself is derived from the same ancient root that gave rise to "panis" in Latin.
