How can write dictum in a sentence?

Answer 1

With a pen, or a pencil, or a typewriter. It would also probably help to have some idea what "dictum" means. I mean, you don't want to write a letter to your crush in which you say "I couldn't help but admire your luscious dictum" and have him or her slap you silly the next time he or she sees you.

That's probably not what you meant to ask, but on the other hand I don't really know what you meant to ask, and you should probably try to work on that.
