Dvoustranný

Dvoustranný is a Czech adjective meaning two-sided or bilateral. It is formed from the roots dva (two) and strana (side) with the adjectival suffix -ný. The feminine form is dvoustranná and the neuter dvoustranné. It is commonly contrasted with jednostranný (one-sided) and, in broader usage, with vícestranný or vícestranný to indicate more than two sides.

The term is widely used to describe physical objects and designs that have two faces or surfaces. Examples include dvoustranný tisk (double-sided printing), dvoustranný list or papír (a sheet printed on both sides), and dvoustranná karta or plakát (two-sided card or poster). In printing, dvoustranný režim refers to the option that prints on both sides of each sheet, often requiring a duplex mechanism.

In social, political, and legal contexts, dvoustranný denotes bilateral relations or agreements between two parties. A dvoustranná dohoda or dvoustranné vztahy describes arrangements or interactions involving two states, organizations, or individuals. The term can also characterize arguments or negotiations that involve two sides or parties, highlighting the two-sided nature of the discussion.

Etymology traces to Czech roots for “two” and “side,” and the word participates in standard inflection patterns for adjectives in -ný. It is commonly used in technical, administrative, and everyday language to specify dual-sided characteristics without implying any value judgment.
