Do the teachings of Catholic Church prohibit the use of “Amen” for purposes other than prayers?

**Amen** is a secular word of Greek and Hebrew origin, and is used to express solemn ratification (as of an expression of faith) or hearty approval (as of an assertion). The Church has been associating the word with prayers from the very beginning, and it finds universal use, albeit with slight variations in diction. One can also find typical circumstances in day-to-day conversation where amen could be used to mean confirmation of something. For instance, a boy can reply to the stern instruction of his father to finish his home-work by 9.00 p.m. by saying "amen" without disrespect to its traditional use. But he does not, for fear of getting reprimanded for misusing a prayer. My question therefore is: **Do the teachings of Catholic Church prohibit the use of *"amen"* for purposes other than prayer?**
