To deem something is to think of it in a particular way, or to judge that it has a particular quality — but in an official, careful voice, not a casual one. You deem a plan necessary, deem a person unfit, deem an idea inappropriate.

To deem something把某件事 deem, is to think of it in a particular way就是用某種特定的方式看待它, or to judge that it has a particular quality或判定它具有某種特質 — but in an official, careful voice但語氣是正式、謹慎的, not a casual one而不是隨便的。You deem a plan necessary你可以說 deem一項計畫必要, deem a person unfit deem一個人不適任, deem an idea inappropriate deem一個想法不恰當。

It is not the everyday verb for “think” or “feel.” You would not text a friend “I deem this pizza good.” The word belongs in law, notices, news, and formal writing, where someone is putting a label on a thing, almost as a ruling. That taste is old: the earlier meaning was close to “judge” or “give a decision,” and a little of that still sits in the modern word.

It is not the everyday verb for “think” or “feel.”它不是「think」或「feel」那種日常用的動詞。You would not text a friend “I deem this pizza good.”你不會傳訊息跟朋友說「I deem this pizza good.」。The word belongs in law, notices, news, and formal writing這個字用在法律、公告、新聞和正式書寫裡, where someone is putting a label on a thing那些場合裡有人是在為某件事貼上判定, almost as a ruling幾乎像是做出裁決一樣。That taste is old這種味道很古老: the earlier meaning was close to “judge” or “give a decision,”較早的意思接近「judge判斷」或「give a decision做出裁決」, and a little of that still sits in the modern word現代這個字裡還留有一點那個味道。

The usual pattern is deem + something + adjective (or “to be” + adjective). Though actually, even in formal English it often hides in the passive: the meeting was deemed a success, the product was deemed unsafe — a tidy way to say “people in charge decided,” without naming who.

The usual pattern is deem + something + adjective常見的句型是「deem + 某事物 + 形容詞」, (or “to be” + adjective)（或加上「to be + 形容詞」）。Though actually不過其實, even in formal English即使在正式英文裡, it often hides in the passive它也常常藏在被動語態裡: the meeting was deemed a success像 the meeting was deemed a success這場會議被視為成功, the product was deemed unsafe或 the product was deemed unsafe這項產品被判定不安全 — a tidy way to say “people in charge decided,”這是一種簡潔的說法，意思是「負責的人做了決定」, without naming who卻不必說出是誰。
