Explanation

คน means “person,” and เดียว means “single” or “only,” so คนเดียว is built around the idea of one person only. The most common pattern is verb + คนเดียว, as in ไปคนเดียว “go alone” or กินข้าวคนเดียว “eat alone.” The word itself does not necessarily imply loneliness; use เหงา if you want to say someone feels lonely.

Usage

It is very common in everyday speech. You will hear it when talking about going somewhere, eating, living, traveling, working, making reservations, or answering whether someone is alone or with others.

Caution

For “do something alone,” คนเดียว is usually more natural than หนึ่งคน. หนึ่งคน sounds more like counting one person. Also, อยู่คนเดียว can mean either “be alone now” or “live alone,” depending on context.

Differences from similar words

1 alone synonyms

2 the only person synonyms

  • เพียงคนเดียว strongly emphasizes “only one person.” คนเดียว can already mean “the only one,” but เพียง adds extra emphasis.

3 one person synonyms

  • หนึ่งคน is the straightforward count “one person.” คนเดียว can also answer a headcount, but it often carries the sense of “just me” or “no one else with me.”
