The Japanese word データ (pronounced "deeta") is a loanword from English, and it means "data." It refers to a collection of facts and figures used as a basis for reasoning, discussion, or calculation. It's information that has been collected and can be analyzed. This can include numbers, text, images, and other types of information.

You use データ in situations where you are talking about information, especially in contexts related to science, technology, research, business, and statistics. It can be used as a noun.

⚫︎ The word is typically written in katakana: データ. ⚫︎ Since it's a loanword, it doesn't have a Kanji representation. ⚫︎ There are no variations in okurigana because it is entirely written in katakana.
