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!
