今日

1. Origins, structure, and basic meaning

• Structure: 今日 is read きょう here, combining now 今 with day 日 to denote the day of speaking.
• Basic usage: It refers to the day on which the utterance occurs, as in 今日は読む, and is read きょう.

2. Common pitfalls and similar expressions

• Grammar and combinations
  • In formal writing the same spelling can be read こんにち for “nowadays” or “the present,” so distinguish that from this reading.
