舅（しゅうと、shuuto）
- father-in-law

The Japanese word 舅, read as しゅうと (shūto), refers to one's husband's father. It specifically means "father-in-law" from a woman's perspective. It's a term of respect, reflecting the hierarchical nature of traditional Japanese family structures.

⚫︎舅に挨拶をする。 Translation: I greet my father-in-law. ⚫︎舅はとても優しい人です。 Translation: My father-in-law is a very kind person. ⚫︎夫の舅にプレゼントを贈った。 Translation: I gave a present to my husband's father (my father-in-law).

This word is used primarily by women when referring to their husband's father. It's considered polite and respectful. In modern Japanese, the usage might vary depending on the relationship with the father-in-law, but it generally indicates a degree of formality. One would use this word when talking about the father-in-law to others, or even in his presence, depending on the context.

The word is typically written with the kanji 舅. The reading is しゅうと in hiragana. There are no other common ways to write this word and no variations in the okurigana.

There aren't direct, commonly used synonyms that completely replace 舅, but depending on context and the level of formality: ⚫︎お父さん (otōsan) - "father" (informal, used with close family members) ⚫︎義理の父 (giri no chichi) - "father-in-law" (more formal)

There is no direct antonym for 舅 in the sense of a single word. However, the closest opposite would be a term referring to the father of one's wife, such as 岳父 (gakufu), but the word is more formal. The antonym, depending on the context, could be other family members that are not the father-in-law.
