eszközén

The term "eszközön" is a Hungarian grammatical construct derived from the preposition *eszközön* (meaning "by means of" or "with the help of") combined with the locative case ending *-n/-on*. In Hungarian, this form is used to indicate the instrument, tool, or method by which an action is performed. It is a locative case construction that specifies the means or instrument involved in a particular process or activity.

In Hungarian grammar, the locative case is used to express various spatial, temporal, or instrumental relationships. When referring to tools or instruments, the preposition *eszközön* (or its shortened form *eszközön*) is often paired with the locative case to indicate how an action is carried out. For example, "ír a tollal" (I write with a pen) can be rephrased as "ír a toll eszközön" (I write by means of the pen), though the former is more common in everyday speech.

The locative case in Hungarian is formed by adding the suffix *-n* or *-on* to nouns, depending on the ending of the base word. For example, "toll" (pen) becomes "tollon" in the locative case, resulting in "tollon ír" (write with a pen). The term "eszközön" itself is not a standalone word but a grammatical construction used to emphasize the instrumental function of the noun it modifies.

This construction is particularly useful in formal or technical writing, where clarity in specifying the method or tool is essential. While it may sound slightly archaic or literary in modern Hungarian, it remains a valid and grammatically correct way to express instrumental relationships. The use of "eszközön" reflects the language's rich morphological system, allowing for precise and nuanced expressions of meaning.
