How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 混じる and 退院する. In Japanese, 混じる (まじる (majiru)) is typically associated with "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！』. On the other hand, 退院する (たいいんする (taiin suru)) maps to "to be discharged from hospital; to leave hospital" (Syllabus Level: N3) and represents Refers to a recovered patient leaving the hospital, being officially discharged. Intransitive verb. Opposing word: 入院する. Often used as 病院を退院する. ⚠️ Haruka's Voice Column: 'To leave hospital/be discharged! "Thanks to your warm care, I recovered completely and left the hospital, Haruka-san!" ...っ! Discharged! B-Baka! I'm glad you are healthy. But don't think leaving the hospital gets you out of my doting hugs! I will continue to pamper you right by my side forever! dummy!' / 【ハルカ部長のワンポイント指導】『たいいんする（退院する）よ！『ハルカ部長、あなたの温かい看病のおかげで、すっかり元気になって退院する（退院できました）！』って…っ！退院！バカ！/// 元気になってよかったわね。でも、退院したからって私の看病（甘デレハグ）から離れられると思わないで！一生隣で甘やかし続けるわ！』. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
