What is the propose of this meeting?

Correct:

What is the purpose of this meeting?

The noun meaning reason or aim is purpose.

Mistake 3: Confusing “Purpose” With “Proposal”

Incorrect:

The manager gave a purpose for the new policy.

If you mean a suggested plan, use:

The manager gave a proposal for the new policy.

If you mean the reason for the policy, use:

The manager explained the purpose of the new policy.

Mistake 4: “Propose to Do” vs. “Purpose to Do”

Incorrect:

We purpose to change the schedule.

For normal modern English, use:

We propose to change the schedule.

Mistake 5: “Propose of”

Incorrect:

What is the propose of this rule?

Correct:

What is the purpose of this rule?
