The Nuance Difference: "専心" vs "疎通"

In Japanese, both 専心 and 疎通 are often translated to English but have distinct usages. 専心 (せんしん (senshin)) represents "devotion, dedication, wholeheartedness, single-mindedness" (Level: N1) and typically represents 一つのことに心を集中させ、他のことに気を取られずに打ち込むことです。特に学問や仕事、趣味などに真剣に取り組む様子を表します。It means to focus one's mind on one thing and devote oneself to it without being distracted by others. It particularly describes the state of earnestly engaging in academics, work, or hobbies.. On the other hand, 疎通 (そつう (sotsuu)) translates to "mutual understanding, smooth communication" (Level: N1) and is used for 情報や意思が滞りなく行き交い、お互いが理解し合える状態を指します。「コミュニケーションの疎通」のように使われることが多いです。It refers to a state where information and intentions flow smoothly, and mutual understanding is achieved. Often used like 'communication no sotsuu'. Mixing these up can sound unnatural to native Japanese speakers!
