The Japanese noun 'ツール (つーる)' means 'tool'. This word is a direct loanword from English and is used to refer to any kind of tool, whether physical (like a hammer or screwdriver) or abstract (like software tools). It is commonly used in both everyday conversation and technical contexts. For example: I need a new tool for my work「仕事に新しいツールが必要です」(しごとにあたらしいつーるがひつようです). This software is a useful tool「このソフトウェアは便利なツールです」(このソフトウェアはべんりなつーるです). The word is typically written in katakana to indicate its foreign origin.
