この（この、kono）
- this

The Japanese word この (kono) is a demonstrative adjective, which means "this" or "this one." It's used to point out or refer to something that is close to the speaker (the person speaking). It modifies a noun and always comes directly before it. この indicates something physically near the speaker, or something recently mentioned or understood.

⚫︎ この本は面白いです。 Translation: This book is interesting. ⚫︎ このペンは誰の？ Translation: Whose is this pen? ⚫︎ この週末は何をしますか？ Translation: What will you do this weekend?

⚫︎ Use この when referring to something that is within the speaker's immediate vicinity, often within arm's reach. ⚫︎ It is also used to refer to something that the speaker has just mentioned or is currently discussing. ⚫︎ When starting a conversation, この can be used to set the context or introduce a topic, such as "この問題は... (This problem is...)"

⚫︎ この is primarily written in hiragana as この. ⚫︎ There is no kanji form for この.

⚫︎ There are no direct synonyms for この in the same way as in English, because Japanese grammar doesn't work the same way. However, other demonstrative adjectives include: ⚫︎ それ (sore): "that" (near the listener) ⚫︎ あれ (are): "that over there" (far from both speaker and listener) ⚫︎ どれ (dore): "which one?"

⚫︎ There are no direct antonyms, but the demonstrative adjectives それ and あれ can be seen as opposites in terms of proximity. それ is near the listener, while あれ is far from both.
