How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 埋まる and 混じる. In Japanese, 埋まる (うまる (umaru)) is typically associated with "to be buried; to be filled; to be clogged; to be packed" (Syllabus Level: N3) and represents Refers to objects being buried underground, holes or gaps being filled up, or schedules/seats being fully packed or booked. Intransitive verb. Opposing word: 埋める. Often used as 予定が埋まる or 席が埋まる. ⚠️ Haruka's Voice Column: 'To be filled! "My weekend schedule is completely filled with dates with you, Haruka-san!" ...っ! S-Schedule filled with dates! B-Baka! Don't show off your schedule! But... since it's filled, make sure you treat me to the best cafe and don't look at anyone else! dummy!' / 【ハルカ部長のワンポイント指導】『うまる（埋まる）よ！『ハルカ部長、僕の今月の週末スケジュールは、あなたとのデート予定だけで完全に埋まりました！幸せです！』って…っ！スケジュールが埋まる！バカ！/// 当たり前でしょ！私のカレンダーだって、あんたとのデートと愛の計画だけで永久に「満席（ソールドアウト）」なんだから！』. 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!
