The term "un profane" refers to something that remains pure and free from any contamination or disrespect. Its antonyms, therefore, include words like "profane," "vulgar," "impious," "irreverent," and "sacrilegious." These terms can be used to describe something that is not sacred or holy, or that fails to demonstrate respect for religion or tradition. Another antonym for "un profane" would be "sanctified," which refers to something that has been consecrated or made holy. Similarly, "reverent," "upright," and "dignified" are other antonyms that can be used to describe something that is pure and virtuous.
