oboustranná

Oboustranná is the feminine singular form of the Czech adjective oboustranný, meaning two-sided, bilateral, or involving two sides. It is used to describe objects, surfaces, or concepts that have two sides or aspects, as well as figurative references to interactions between two parties. The root is obě (both) plus strana (side), with the suffix -ná. The form agrees with the noun’s gender and number, for example oboustranný (masculine), oboustranná (feminine), oboustranné (neuter or plural).

In usage, oboustranná appears in contexts such as printing or manufacturing to indicate double-sided printing or surfaces (for instance, oboustranná tiskovina). It is also employed in discussions of bilateral or reciprocal relations between entities, such as oboustranné vztahy mezi státy. The term is common in technical writing, education, and diplomacy, where precision about two-sidedness or two-party interaction is required.

Etymology-wise, oboustranná derives from obě strany, meaning both sides, with the typical adjectival suffix -ná. It is related to other forms like oboustranný and oboustranné and is often interchangeable with synonyms such as dvoustranný or bilaterální, depending on style and the noun it modifies.
