gumovou

Gumovou is the instrumental singular form of the Czech adjective gumová, which means rubber or made of rubber. It does not function as a stand-alone word but as a grammatical form used to describe feminine nouns in specific cases, most commonly the accusative and instrumental.

In Czech, adjectives decline with gender, number, and case. For the feminine singular, the forms include gumová (nominative), gumové (genitive and dative), and gumovou (accusative and instrumental), among others. Therefore gumovou can appear in phrases where a feminine noun is in the specified cases, such as gumovou hračku (a rubber toy, accusative) or s gumovou hračkou (with a rubber toy, instrumental).

Typical usage centers on describing objects or materials made of rubber or possessing rubber-like properties. Examples include sentences such as: Koupil jsem gumovou hračku. (I bought a rubber toy.) Použil jsem gumovou pásku. (I used a rubber tape.) S gumovou hračkou si hrál. (He played with a rubber toy.)

Etymology and related forms: gumová derives from the noun guma (rubber). The same adjective also appears in other gender and number forms to agree with different nouns and cases, illustrating standard Czech adjective declension.

Overall, gumovou is a common inflected form used in everyday Czech to describe feminine nouns in the accusative or instrumental case when the attribute is about rubber or rubber-like characteristics.
