person you spend time with
A person who is often with you, for friendship, support, or when you travel.
用法パターン：
[someone]'s companion; a companion on [a trip]
よくある間違い：
Learners sometimes use "companion" too often where "friend" is more natural in everyday speech. "Companion" sounds slightly more formal or literary, and is common in writing or careful speech. Also, do not confuse "companion" (a person) with "company" (the state of being with others or a business).
類義語
friend (More common and casual; does not always suggest spending as much regular time together as 'companion' can.)
|
partner (Often suggests a romantic or life partner, or someone you share a project with; 'companion' is broader.)
対義語
stranger (Someone you do not know or spend time with is the opposite of a familiar companion.)
|
enemy (An enemy is someone you are against, rather than someone who keeps you company.)
