Hello.

Please help me with the verb "purpose". Is it possible to use it in the sentence "The latest terrorist attack is purposed to intimidate the world" or is it used in a different meaning or a different form (if yes, will you please give a short example).
Thank you very much.

It would be better to use "supposed" in that sentence, not "purposed."

or

The purpose of the latest terrorist attack is to intimidate the world.

Most of the time, "purpose" is used as a noun; rarely is it used as a verb:
