linha

Linha is a Portuguese noun meaning line, row, or string, and it appears in a range of contexts centered on the idea of connection, order, or sequence. It can denote a geometric line in mathematics, typically a straight or curved mark that extends between points, and it can also refer to any line or border on a surface.

In writing, linha refers to a line of text or poetry and functions as a basic unit in typography and layout. In visual art and design, it denotes a line as an element of composition, conveying contour, movement, and structure. In music, a linha may describe a melodic line or a bass line, and in notation lines (staffs) are the horizontal guides for notes.

In transportation and infrastructure, linha is widely used to describe a service route, such as a bus line, tram line, or railway line. In industry and technology, linha can refer to a production line as well as to data or telecommunications lines used for communication or signal transmission.

In everyday speech, linha can mean a queue or row of people or objects, and it appears in several fixed expressions, for example linha do tempo for a timeline or linha de comando for the command line interface. Etymologically, linha derives from Latin linea, meaning thread or line, and it is cognate with the English word line.

Notes: The term is common across Portuguese-speaking regions and adapts to many specialized and everyday uses, reflecting the broad sense of connection, order, and sequence that underpins the concept of a line.
