学級（がっきゅう、gaっkyuu）
- class (school)

The Japanese word 学級 がっきゅう refers to a class or grade in a school setting. It encompasses the group of students who are taught together, and the place where they learn. Think of it as a specific level or group within a school's organizational structure. It often implies the group of students assigned to a particular teacher for a specific subject or for all subjects in elementary school.

⚫︎ あの学級には、30人の生徒がいます。 Translation: There are 30 students in that class. ⚫︎ 私は小学校の6年生の学級です。 Translation: I am in the 6th-grade class of elementary school.

You use 学級 when talking about a specific class or grade level within a school. It's used to identify a group of students, the location of the classroom, or the educational setting itself. You can also use it to specify the class you belong to or the class of someone else.

学級 is primarily written using kanji and hiragana: 学級。 The kanji 学 (gaku) means "study" or "learning," and 級 (kyū) means "class," "grade," or "rank." It is never written in katakana. There are no variations in okurigana.

⚫︎ クラス (kurasu) - class (loanword from English), used more casually. ⚫︎ 組 (kumi) - a class or group (especially in elementary or junior high school). ⚫︎ 学年 (gakunen) - grade level.

There aren't direct antonyms, but words referring to outside the classroom or school could be considered as contrasts: ⚫︎ 学校 (gakkō) - school ⚫︎ 家 (ie/uchi) - home
