fossilními

Fosilní is a Czech adjective meaning fossil or relating to fossils. The form derives from the Latin fossilis and has entered Czech through scientific terminology. In standard Czech, the spelling used is fosilní with a single s. The variant fossilní (with double s) is not considered correct in normative Czech and is generally regarded as a misspelling or erroneous transliteration influenced by English spelling.

Usage and meaning

Fosilní is commonly used in geology, paleontology, archaeology, and related sciences to describe things derived from or associated with fossils. It is also found in everyday language when referring to fossil fuels, such as coal, oil, and natural gas, and in phrases describing fossil remains or structures. The word can modify nouns of any gender and number, taking appropriate endings according to Czech declension.

Morphology

As an ordinary Czech adjective, fosilní declines according to gender, number, and case. Its instrumental plural form is fosilními (for example, fosilními zbytky – with fossil remains). The commonly observed nonstandard form fossilními is regarded as incorrect in formal writing.

- fosilní paliva (fossil fuels)
