Usage
What does companion mean? A companion is a person who frequently spends time with you, associates with you, or accompanies you when you go places. Pets are also commonly considered companions. The word companion implies that you spend a lot of time together. A person you call a companion can be a friend or a romantic partner. A travel companion is someone you travel with. Companionship is the state of spending time with someone or having someone to spend time with—the state of having a companion or being someone’s companion. Sometimes, a hired helper is called a companion, especially when they help to take care of an older person. Companion is sometimes also used to refer to a thing that accompanies or complements something else, such as in the phrase companion piece, which often refers to an artistic work that pairs well with another work. More specifically, a companion refers to a handbook, guidebook, or field guide (the word is especially used in the titles of such books). In astronomy, companion is used in a more specific way to refer to a companion star—the less bright star in a set of stars called a double star. (The brighter star is called the primary.)Example: People make fun of older people for using dating sites, but the truth is that a lot of them are just lonely and looking for a companion.

Etymology
Origin of companion1
First recorded in 1250–1300; Middle English compainoun, from Anglo-French; Old French compaignon, from Late Latin compāniōn- (stem of compāniō ) “messmate,” equivalent to com- “with, together” + pān(is) “bread” + -iōn- noun suffix; presumably as translation of a Germanic word; compare Gothic gahlaiba, Old High German galeipo; see com-, -ion
Origin of companion2
First recorded in 1730–40; alteration of Dutch kampanje “quarterdeck,” possibly from Italian compagna “pantry (of a ship)”
Explanation
A companion is one who serves as a friend or partner in something. Whether it’s travel or dinner or card-playing, your companion is the one who does it with you. The word companion is a close, um, companion to the word company, and you might as well say that someone you keep company with is your companion. Sometimes, it describes a piece of art or other work that goes with another. For instance, you might read a biography of Emily Dickenson as a companion to her studying her poems. The things go together and complement each other.
