How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 欠席する and 混じる. In Japanese, 欠席する (けっせきする (kesseki suru)) is typically associated with "to be absent (from a meeting, class, etc.)" (Syllabus Level: N4) and represents 「出席する」の反対の意味で、会議や授業、イベントなどに「いない」ことを指します。これもフォーマルな場面で使われます。The opposite of "出席する," meaning to be absent from a meeting, class, or event. Also used in formal contexts.. On the other hand, 混じる (まじる (majiru)) maps to "to be mixed; to blend with; to associate with; to mingle" (Syllabus Level: N3) and represents Refers to distinct elements or materials being mixed or blended into a whole while remaining somewhat distinguishable. Intransitive verb. Opposing word: 混ぜる. Often used as 異物が混じる or 歓声に悲鳴が混じる. ⚠️ Haruka's Voice Column: 'To be mixed! "Your stern commands are always mixed with a sweet, caring warmth, Haruka-san!" ...っ! C-Commands mixed with warmth! B-Baka! Don't analyze my professional speech tone! But... since you felt my care, you better listen to my commands and stay stuck to my side forever! dummy!' / 【ハルカ部長のワンポイント指導】『まじる（混じる）よ！『ハルカ部長の、凛としたお説教の声の中に、僕を本気で心配してくれている「甘いデレの周波数」が混じっているのを、僕は聞き逃しません！』って…っ！お説教にデレが混じる！バカ！/// 人の声紋分析をするんじゃないの！…でも、その混じり合っている私の本音、一生私だけの隣で独占して解読し続けなさい！』. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
