Silnou

Silnou is a form of the Czech adjective silný, meaning strong. It is the feminine singular form used in the accusative case or the instrumental case, describing feminine nouns. For example, in the accusative you would say “silnou ženu” (a strong woman), and in the instrumental you might encounter phrases like “s silnou vůlí” (with a strong will). As a typical attributive or predicative adjective, silnou appears when the noun it modifies is feminine and singular.

Etymology and cognates: Silný originates from the Proto-Slavic root *sílъ, related to strength or force. The word has cognates across Slavic languages, such as Slovak silný, Polish silny, and Russian силный (síl’nyj), all tracing back to a common Indo-European root related to power and vigor.

Usage notes: Silnou is used in everyday Czech to convey physical or figurative strength. It is not a standalone noun; it functions as an adjective that agrees with a feminine noun in gender and case. The base form in masculine is silný and in feminine nominative is silná, with silnou representing the feminine singular accusative or instrumental forms.
