1. Today: This is the most common meaning, especially when written in hiragana: 今日 (きょう).
2. Respectful "you": This is less common, but it can be used in very formal situations when written in kanji: 卿 (きょう).
3. "Class": This is a more specialized meaning, used in the context of school or university, and usually written in kanji: 課 (か).
4. "Section": This meaning is also less common and typically written in kanji: 協 (きょう).
To determine the correct meaning, you need more context.
For example:
* "Kyou wa atsui desu ne." (今日は暑いですね。) This means "It's hot today."
* "Kyou no gakkou wa omoshirokatta desu." (今日の学校は面白かったですよ。) This means "School was interesting today."
* "Kyou wa nanika shiteimasu ka?" (卿は何かしていますか？) This means "Are you doing anything today?" (This is very formal and rarely used).
Please provide more context about the specific instance where you encountered "Kyou" so I can give you the most accurate translation.
