inkoustem

Inkoustem is the instrumental singular form of the Czech noun inkoust, meaning ink. In grammatical terms, it marks the instrument with which an action is performed and is commonly used with verbs of writing, drawing, or printing.

The noun inkoust is masculine inanimate. Its instrumental singular form is inkoustem, formed by adding the standard instrumental suffix -em to the stem inkoust. This pattern is typical for many hard-stem masculine nouns in Czech, and inkoustem is the conventional way to express “with ink” in the instrumental case.

Examples of usage include:

- Psal inkoustem na pergamen. (He wrote with ink on parchment.)

- Obraz byl kreslen inkoustem a štětcem. (The image was drawn with ink and a brush.)

- Dokumenty byly podepsány inkoustem. (The documents were signed with ink.)

Origin and scope: Inkoust is the common Czech term for the writing fluid used in traditional writing and printing. Inkoustem, as the instrumental form, is not a separate lexical item but a grammatical variation of inkoust that indicates the instrument. The form follows standard Czech rules for masculine inanimate nouns and their instrumental endings.
