What does span mean?
Span is a versatile word expressing the idea of extending or being extended across something. As a verb, it describes an activity, period, or subject that stretches across a particular span of time, crosses a physical distance, or encompasses a range of matters. As a noun, a span can be a continuous stretch of time, the distance between two points, or a bridge or one of the sections that form a bridge. The word is standard in both formal and informal English and is especially useful in journalism, biography, science, and engineering. Its flexibility allows the same word to describe the duration of a career, the reach of a proposal, the breadth of an exhibition, and the structure that carries a road over a river. Although it may occasionally sound somewhat literary in phrases such as "the span of a lifetime," span remains a direct, familiar, and precise alternative to longer expressions like "a period lasting" or "to extend across."
A continuous stretch of time, a distance between two points, or a bridge or bridge section extending across a gap.
"The project was completed in a span of just six months."
To extend over or across a period of time, physical distance, or range of subjects.
"The investigation spanned several countries and decades."
The regular plural is used for separate stretches, distances, or bridge sections.
"The bridge consists of three spans supported by concrete piers."
A bridge is a span in engineering, a decade is a span in history, and a sentence can span both space and time.
