The phrase "are adjacent" is often used to describe two objects or things that are situated next to each other. The spelling of this phrase can be explained using IPA phonetic transcription. The first word "are" is pronounced /ɑː(r)/, with the long "a" sound and a silent "r". The second word "adjacent" is pronounced /əˈdʒeɪsnt/, with the schwa sound in the first syllable and a "j" sound in the second. This word is also spelled with the suffix "-cent," which means "to be centered around" or "to be located in the middle of."
"Are adjacent" is a phrase commonly used in both mathematics and general contexts to describe objects or entities that are located next to or in close proximity to each other. It implies a neighboring relationship, suggesting that two or more things share a common side, edge, or boundary.
In mathematics, the term "adjacent" primarily refers to two geometric figures that share a common side or vertex. For example, in a square or rectangle, the two sides that meet at a corner are considered adjacent. Similarly, in a triangle, the sides that intersect at a vertex are said to be adjacent sides. This concept extends to three-dimensional objects as well, with adjacent faces, edges, or vertices in a cube, pyramid, or other polyhedrons.
Outside of mathematics, the expression "are adjacent" can also be used to describe objects or entities in various contexts. For instance, in everyday language, it can apply to physical locations or objects that are situated side by side, such as adjacent rooms, adjacent houses, or adjacent city streets. It can also denote temporal relationships, such as adjacent hours, adjacent months, or adjacent years, indicating consecutive or consecutive periods of time.
In summary, the phrase "are adjacent" refers to the spatial or temporal proximity between two or more objects, where there is a shared boundary, side, or vertex, either in a mathematical or general sense.
The phrase "are adjacent" does not have a specific etymology as it is composed of two separate words.
The word "are" is the plural form of the verb "be", which comes from the Old English word "earun" or "eron". It can be traced back to Proto-Germanic and is related to similar words in other Germanic languages.
The word "adjacent" comes from the Latin word "adjacēre", which means "to lie near". It is derived from the combination of the prefix "ad-" meaning "to" or "near" and the verb "jacēre" meaning "to lie". This Latin word was later adopted into Middle English as "adjacent" with the same meaning.
