前提（ぜんてい、zentei）
- premise

The Japanese word 前提 (ぜんてい) means "premise," "assumption," or "precondition." It refers to something that is accepted as true or given before you begin discussing or doing something else. It forms the basis or foundation upon which further discussion, actions, or arguments are built. The word implies that without this [前提] being valid, the subsequent conclusions or actions might not be correct or effective. It can be a statement or fact, or even an implicit understanding.

⚫︎この話の《前提として、彼はすでにその事実を知っているとします。》 Translation: As a premise for this story, let's assume he already knows that fact. ⚫︎成功のためには、十分な資金があることが《前提です。》 Translation: Having sufficient funds is a precondition for success. ⚫︎議論の《前提をまず確認しましょう。》 Translation: Let's first confirm the premises of the discussion.

You use 前提 when you want to establish the basic understandings or conditions before proceeding. ⚫︎It's common at the beginning of discussions, presentations, or arguments to clearly define the [前提]. ⚫︎It can be used to set the stage or provide context for understanding a situation or a set of facts. ⚫︎You can use it to highlight what needs to be true for something else to follow. ⚫︎It can also be used to question the basis of an argument, highlighting that the [前提] itself might be flawed.

前提 is typically written in kanji (前提) with the reading in hiragana (ぜんてい). There are no other common ways to write this word. The okurigana is fixed.

The word 前提 is a compound word formed from two kanji. 前 (ぜん) means "before" or "prior," and 提 (てい) means "to propose" or "to offer." Together, they indicate something that is proposed or offered beforehand, setting the stage for what comes after. It's essentially the foundation laid down [前] the main discussion.
