Épülésén

Épülésén is a Hungarian inflected form derived from the noun épülés, which denotes development, growth, construction, or rebuilding. The form épülésén combines the possessive suffix -e (marking its/its) with the adessive case suffix -en/-ön/-ön, yielding a meaning related to location or state: “on its development” or “in its development.” In practice, épülésén is used to refer to events, actions, or processes occurring at or during the development of something.

Etymology and morphology: épülés comes from the verb épülni (to be built, to develop). The noun is nominalized with -és to form épülés (development/building). Adding the possessive suffix -e creates épülése (its development), and the case ending -n attaches to form épülésén, indicating a locative or instrumental sense such as “on/at its development” or “in its development.” The exact interpretation depends on context, particularly the surrounding verbs and nouns.

Usage and context: épülésén is most likely to appear in technical, planning, or formal writing where one discusses a project, plan, or entity and refers to what happens during its development. It can be found in phrases like “az épülésén dolgozó szakértők” (experts working on its development) or “az épülésén történt módosítások” (modifications that occurred in its development). As a specialized grammatical form, it is less common in everyday speech.

Related terms: épülés (development, construction), fejlődés (progress, development), építés/építkezés (building, construction). The choice among these terms reflects nuances between growth, progress, and physical rebuilding in Hungarian.
