The state or relationship of being companions; companionship or the bond between companions.
From companion + -age (suffix indicating state, condition, or collection). The -age suffix typically creates nouns referring to a status or collection, like 'marriage' or 'heritage.'
Companionage is delightfully archaic—it appears in medieval and early modern texts to describe the official relationship between knights, squires, and travelers, making it sound almost like a feudal legal status, when it really just meant 'friendship.'
