The word "vector" is spelled vek-tər (/ˈvɛk.tər/) in the International Phonetic Alphabet (IPA). The first syllable starts with the "v" sound, followed by the "e" sound pronounced as "eh" and emphasized with stress. The second syllable begins with the "k" sound, followed by the "t" sound and finally the "er" sound pronounced as "ər". The spelling of "vector" is derived from its Latin origins, where "vector" means "carrier" or "one who carries".
A vector is a mathematical object that is commonly represented as an arrow or a line segment with both magnitude and direction. In mathematics, a vector specifies a quantity that has both magnitude, which refers to its size or length, and direction, which indicates its orientation or position relative to a reference point or coordinate system.
Vectors can be described in two-dimensional or three-dimensional spaces, and they can be used to represent a wide range of physical quantities such as force, velocity, acceleration, displacement, and electric or magnetic fields. In physics, vectors are often used to depict the movement of objects, with their length representing the magnitude of the quantity being measured and their direction indicating the way in which the object is moving.
In mathematics, vectors can be added or subtracted by aligning them head to tail and drawing a new vector connecting the tail of the first vector to the head of the second vector. The result is a vector that represents the combination of both magnitude and direction. Vectors can also be multiplied by a scalar, which is a number that only affects the magnitude of the vector, leaving its direction unchanged.
Overall, vectors are a fundamental concept in mathematics and physics, providing a useful and intuitive way to represent and manipulate quantities that have both size and direction.
Term noting an insect or any living carrier which transports a pathogenic microorganism from the sick to the well, inoculating the latter; the organism may or may not pass through any developmental cycle within the vector.

The word "vector" has its origins in Latin. It is derived from the Latin word "vector", meaning "carrier" or "bearer". This Latin word is derived from the verb "vehere", which means "to carry" or "to transport". The concept of a mathematical vector was introduced in the 18th century, and the term "vector" was then used to describe quantity with both magnitude and direction.
