Pronunciation: [ˈə͡ʊbləs] (IPA) 
The word "obelus" is a Greek term used to denote a symbol that resembles a minus sign (∧). Its spelling is rather straightforward, as it is pronounced as /ɑbɪləs/. The first syllable (obe) is pronounced as "oh-bee," and the second syllable (lus) like "luhs." The letter "o" in "obelus" is pronounced as a long "o" such as "oh," and "b" is a voiced bilabial plosive. The final syllable "us" is pronounced as "uhs."
An obelus is a term used in several contexts, denoting either a punctuation mark or a structural object. As a punctuation mark, an obelus is represented by a symbol resembling a small minus sign – (÷) or sometimes a simple horizontal line (−), typically used to indicate division in mathematical or numerical expressions. It is commonly employed in mathematical equations, where it separates the numerator and denominator, signifying a quotient or the result of division.
Additionally, obelus refers to a structural object that can be seen in ancient architecture. Historically, an obelus was a tall and slender, four-sided monument resembling a pyramid, typically made of stone and tapering towards a pointed top. Originating in ancient Egypt, obelisks were often inscribed with hieroglyphs or other symbolic representations. They were prominent symbols of power, used to commemorate pharaohs or deities. Obelisks were also popular in the Greek and Roman cultures, serving decorative purposes in both public spaces and memorials.
In summary, the term obelus has two distinct meanings. It can refer to a punctuation mark (– or ÷) utilized in mathematical equations to indicate division. Furthermore, obelus can also describe an ancient architectural monument, particularly a tall, four-sided stone structure, often inscribed with symbolic representations or hieroglyphs, serving as a visual symbol of power or commemoration.
In anc. Mss., the mark (-) or (÷) inserted, particularly in those of the septuagint, to indicate that the passage so marked is not found in the Hebrew; the line thus (-) in modern writing is employed to mark the place of a break in the sense where it is suspended, or when some awkward grammatical transition is made, but is often used instead of a(;) or(:).

The word "obelus" is derived from the Ancient Greek word "obelos" (ὀβελός), meaning "a sharpened point" or "a spit". In Ancient Greece, this term referred to a pointed iron rod or a sharp tip used for cooking or skewering. The usage of the term expanded in later times to refer to a specific punctuation mark that looks like a horizontal line with a dot above and below it (÷). This symbol, known as an obelus, was used in manuscripts and text annotations to mark sections or lines considered dubious or requiring further clarification. Over time, the word obelus has become widely used to describe this particular punctuation mark.
