The word "coextend" is formed from the combination of two parts: "co-" and "-extend".
The prefix "co-" is derived from the Latin word "cum", meaning "together" or "with". It is commonly used in English to indicate jointness, cooperation, or mutual involvement.
The second part, "-extend", is derived from the Latin word "extendere", which means "to stretch out" or "to extend". In English, the suffix "-extend" is used to indicate the act of making something longer or larger in spatial or temporal dimensions.
Therefore, the etymology of "coextend" suggests the notion of extending or stretching something out together or in conjunction with something else. It implies a shared or simultaneous extension of two or more entities.
