辞書（じしょ、jisho）
- dictionary

The Japanese word 辞書 （じしょ） means "dictionary". It's a fundamental tool for language learners and anyone who wants to look up the meaning, pronunciation, or usage of words. A 辞書 provides definitions, example sentences, and sometimes even etymological information.

⚫︎ 日本語の辞書 Translation: A Japanese dictionary ⚫︎ 英語の辞書 Translation: An English dictionary ⚫︎ 辞書で言葉の意味を調べます。 Translation: I look up the meaning of words in the dictionary.

⚫︎ You would use 辞書 anytime you need to find the meaning of a word you don't know. ⚫︎ It is also used to check the spelling or pronunciation of a word. ⚫︎ It can be employed to explore how a word is used in different contexts through example sentences.

⚫︎ 辞書 is primarily written in kanji: 辞書. ⚫︎ The reading, in hiragana, is じしょ. ⚫︎ There are no common variations in the okurigana.

⚫︎ There are no direct perfect synonyms for 辞書 that are used in common everyday conversation. However, the type of 辞書 may be specified: ⚫︎ For instance, a 国語辞書（こくごじしょ) is a Japanese language dictionary. ⚫︎ An English dictionary could be referred to as a 英和辞書 (えいわじしょ). ⚫︎ 辞典（じてん) is sometimes used as a broader term that encompasses encyclopedias or reference books. However, it's not a direct synonym.

There aren't really antonyms for 辞書 because it is a tool. However, the opposite of needing a 辞書 would be knowing the meaning of a word already.
