suggested plan or offer
A plan or offer that someone gives you so you can decide if you want it or not, often in business or work.
用法パターン：
a [business] proposition for/to [someone]
よくある間違い：
Learners often use *proposition* instead of *proposal* in everyday situations like weddings or school events. In most casual contexts, *proposal* is more common (e.g., *marriage proposal*, not *marriage proposition*). *Proposition* often sounds more formal or business-related.
類義語
proposal (Very close in meaning, but often slightly more neutral; proposition can sound more businesslike or strategic.)
対義語
rejection (Refers to the act of saying no to a proposition, the opposite response to accepting or considering it.)

task or situation to handle
A thing you must do or deal with, thought of as easy, hard, good, or bad.
用法パターン：
a [adjective] proposition
よくある間違い：
Learners sometimes confuse this use with the ‘offer’ meaning and try to say *make a tough proposition* when they actually mean *face a tough situation*. Here, *proposition* is usually used with an adjective to describe how difficult or easy something is, not as something you give to someone.
類義語
undertaking (Very similar, but slightly more formal and focused on the act of doing something rather than judging it.)
対義語
breeze (Informal term for something very easy, often used as the opposite of a tough or difficult proposition.)

make a sexual advance
To ask someone, often a stranger, to have sex with you in a very direct way.
用法パターン：
to proposition [someone]
よくある間違い：
Learners sometimes think *proposition* as a verb is neutral, like *suggest*. In fact, it is usually about sex and often sounds negative or inappropriate. Do not use it when you mean to politely *propose an idea* or *suggest a plan*.
類義語
hit on (Informal phrasal verb for flirting or making sexual advances; often sounds lighter and less blunt than proposition.)
対義語

類義語

対義語
