Yhtälöillänsä

Yhtälöillänsä is a Finnish word that translates to "with their equations" or "by their equations." It is a possessive form of the word "yhtälö," which means "equation" in English. The suffix "-nsä" indicates possession by a third person, either singular or plural. Therefore, "yhtälöillänsä" signifies that the equations belong to, are used by, or are related to a "them" or "their."

This word is commonly encountered in academic or scientific contexts, particularly in mathematics, physics, chemistry, and engineering. It is used to describe situations where a particular group of individuals, a specific theory, or a set of phenomena is characterized by or explained through a collection of equations. For example, one might say that a scientist's research is defined by "yhtälöillänsä," meaning their work is characterized by the specific equations they utilize or have developed. Similarly, in discussing a complex system, one could refer to "järjestelmän yhtälöillänsä" to indicate the equations that govern that system. The context in which "yhtälöillänsä" appears will clarify the exact nature of the relationship between the equations and their possessors.
