How do you use the instrumental case to describe how something is done?

What Is the Instrumental Case in Czech?

The instrumental case is one of the seven grammatical cases in the Czech language. Its primary function is to indicate the means, tool, or manner by which an action is performed. In English, this is often expressed using the prepositions “with,” “by,” or “using.” For example, in the sentence “I write with a pen,” the word “pen” would be in the instrumental case in Czech.

How to Form the Instrumental Case

To use the instrumental case correctly, you must first know how to form it. The endings for the instrumental case differ based on gender and number.

Instrumental Case Endings

• Masculine Singular: -em or -ím (for animate nouns), -em (for inanimate nouns)
• Feminine Singular: -ou or -í
• Neuter Singular: -em or -ím
• Plural (all genders): -y, -mi, or -ami

It is important to consult a declension table or a Czech grammar resource to determine the correct ending for each noun. Adjectives and pronouns must also agree with the noun in gender, number, and case.

Using the Instrumental Case to Describe How Something Is Done

One of the most common uses of the instrumental case is to describe the means or method by which an action is performed. This includes tools, instruments, modes of transportation, languages, and sometimes even company (with whom an action is done).

Describing Tools and Means

Whenever you want to say that something is done with a certain tool or object, use the instrumental case:

• Píšu perem. (I write with a pen.)
• Jím lžící. (I eat with a spoon.)
• Řežu nožem. (I cut with a knife.)

Describing Methods and Manner

The instrumental case can also indicate how something is done, especially when paired with adverbs or nouns describing manner:

• Mluvím česky. (I speak Czech.)
• Cestuji autobusem. (I travel by bus.)
• Platím kartou. (I pay by card.)

With Whom Something Is Done

The instrumental case is also used after the preposition s (with) to express company:

• Jdu s kamarádem. (I am going with a friend.)
• Studuji s učitelem. (I study with the teacher.)

Common Prepositions Used with the Instrumental Case

Several prepositions require the instrumental case, the most notable being:

• s/se (with)
• nad (over, above)
• pod (under, below)
• před (in front of, before)
• za (behind, after, for – in the sense of in exchange for)
• mezi (between, among)

For example, “Jsem mezi přáteli.” (I am among friends.)
