English almost never uses this word by itself.

English英文 almost never uses this word by itself幾乎不會單獨用這個字。

You meet it in the Latin phrase in absentia, which means “while the person is not there.” Courts use it: someone can be tried in absentia, or found guilty in absentia, when they should be in the courtroom but are not — they have fled, they are in another country, they refuse to come. An official body can also pass a decision in absentia.

You meet it你會在拉丁片語 in the Latin phrase in absentia裡看到它, which means "while the person is not there."意思是「當事人不在場」。Courts use it法院會這樣用：someone can be tried in absentia有人可以被缺席審判, or found guilty in absentia或被缺席判決有罪, when they should be in the courtroom but are not當他們理應出庭卻沒有出現 — they have fled, they are in another country, they refuse to come可能是逃跑了、人在國外，或拒絕出庭。 An official body官方單位 can also pass a decision in absentia也可以在當事人缺席的情況下做出決定。

Though actually, this is a lawyer’s and news-writer’s phrase, not a word for daily conversation. You would not say “my absentia” for “I wasn’t there.” For ordinary life, say “I was away” or “he missed the meeting.” Keep absentia for that formal setting where a decision is made about you and you are not in the room.

Though actually不過事實上, this is a lawyer's and news-writer's phrase這是律師和新聞寫作用的說法, not a word for daily conversation不是日常對話會用的字。 You would not say你不會說 "my absentia" for "I wasn't there."「my absentia」來表示「我沒去」。For ordinary life日常生活裡, say "I was away" or "he missed the meeting."就說「I was away」或「he missed the meeting」。Keep absentia for that formal setting把absentia留給那種正式場合，where a decision is made about you and you are not in the room也就是有人在做關於你的決定，而你人不在場的時候。
