Translation guide
The English word "trio" refers to a group of three people or things, often with a sense of unity or collaboration. In Japanese, the most common and natural way to express this is with the counter 三人 (sannin) for people, or by using words like 三つ組 (mitsugumi) for objects. The choice depends on what is being counted and the context.
Referring to three people together, such as friends, performers, or a team.
The standard way to say 'three people'. It can be used in almost any context.

三人 (sannin) is the general counter for three people and can be used in any situation. トリオ (torio) is a loanword that often implies a formal or performance-based group, like musicians or comedians. For everyday groups of three friends, 三人 is more natural.

あのトリオは人気がある。

In English, 'trio' can sound slightly formal or specific. In Japanese, it's often more natural to simply state the number and the noun, e.g., 三人 (three people) or 三つ (three things), rather than using a word that explicitly means 'trio'.
