Yes, the word ‘Bible’ is considered a proper noun. This is because it refers specifically to a unique collection of religious texts that are central to Christianity and Judaism.
A proper noun is the name of a specific person, place, or organization, and it is always capitalized. In this case, ‘Bible’ denotes a specific book like no other, composed of various texts written by different authors over centuries. This uniqueness is what classifies it among other proper nouns.
Additionally, when we refer to the Bible, we often mean the Christian Bible, which includes the Old and New Testaments; however, it may also refer to other versions that cater to different denominations or religious contexts. The distinctiveness of these texts further solidifies its status as a proper noun.
