Not a judge in a public court, though the job feels close. People pick an arbitrator because they know the subject, or because both sides trust them.

Not a judge in a public court不是公開法庭裡的法官， though the job feels close雖然這工作感覺很接近。 People人們 pick an arbitrator選仲裁人 because they know the subject因為他們懂那個領域， or because both sides trust them或因為雙方都信任他們。

It is a noun: the person. (The doing is arbitrate; the process is arbitration.) It belongs to work, contracts, and law, not to playground talk.

It is a noun這是名詞： the person指那個人。 The doing is arbitrate動詞是arbitrate（仲裁）； the process is arbitration過程叫arbitration（仲裁程序）。 It belongs to work, contracts, and law這個字屬於工作、合約和法律的場合， not to playground talk不是遊樂場閒聊會用的字。

Though actually, there may be one arbitrator or a small panel of three; the word still names each person who has that deciding job, not the meeting itself.

Though actually不過， there may be one arbitrator or a small panel of three可能只有一位仲裁人，也可能是三人小組； the word still names each person who has that deciding job這個字指的還是每一個有這種裁決工作的人， not the meeting itself不是指那場會議本身。
