couplet

two items of the same kind

two consecutive lines of verse, equal in length that usually rhyme

A couplet is a pair of consecutive lines of poetry that usually rhyme and have the same meter. Couplets can stand alone as a complete thought or idea, or they can be part of a larger poem. This form is often used to create a sense of closure or emphasis, making it a popular choice in various poetic traditions. Couplets are common in both formal poetry and more modern works, and they can add musicality and rhythm to the verse.

a pair of parallel, one-way streets that run in opposite directions to help manage traffic flow in urban areas

A couplet is a pair of streets that run parallel to each other, usually in opposite directions. These streets are often part of a traffic system designed to improve flow and reduce congestion by allowing vehicles to move in different directions on separate roads. A couplet typically functions by providing an efficient route for drivers to travel through a city or area, with each street in the couplet handling traffic going one way. This design helps manage traffic more effectively, especially in busy or densely populated areas.
