Etymology:

Pevný derives from the Proto-Slavic root *pevъ, meaning firm or solid. It has cognates across Slavic languages, and in many languages it yields words related to firmness, certainty, or solidity, such as Czech pevný, Polish pewny (certain), and related terms in other Slavic tongues.

Usage notes:

Pevný is common in both concrete and abstract contexts. It can describe physical properties, constructions, or materials (pevným materiálem – with solid material) as well as abstract states like resolve or belief (pevnou vírou). The instrumental form pevným is the standard way to express “with a firm [something]” or “in a firm manner.”
