When to use suppose vs supposed?

"Suppose" and "supposed" are both words related to assuming or assuming something to be true, but they have different grammatical functions.

Suppose is a verb, meaning:

* To assume something is true for the sake of argument: "Suppose you win the lottery, what would you do?"

* To suggest or propose something: "I suppose we could go to the movies."

Supposed is an adjective, meaning:

* Believed to be true, but possibly not: "He's supposed to be a good student, but his grades are slipping."

* Intended or expected: "The meeting was supposed to start at 10:00."

Here's a simple way to remember the difference:

* "Suppose" is a verb that tells us what we're thinking or assuming.

* "Supposed" is an adjective that describes something as being assumed or expected.

Here are some examples:

* Suppose you could fly, where would you go? (verb)

* He is supposed to be here by now. (adjective)

* Suppose we go to the beach this weekend. (verb)

* The book is supposed to be very interesting. (adjective)

In short, use "suppose" when you are suggesting, assuming, or proposing something. Use "supposed" when you are describing something that is believed or expected to be true.
