Choosing the right word

    na-adjective, nounCovers cool-headed in the sense of judging things dispassionately, without emotion clouding one's thinking. It often carries a hint of coldness or detachment, describing a person whose decisions stay rational even under pressure.
  • クールCommon
    na-adjectiveA loanword covering cool in the sense of calm and collected — a composed, unruffled manner. It can also mean cold-hearted, so the same word may praise someone's poise or suggest emotional distance; context decides.
    彼女かのじょのクールな視線しせんに、俺おれはドキッとした。↗
