piirteistää

Piirteistä is a Finnish noun form that means “of the features” or “from the characteristics.” It is the plural elative form of piirre, which refers to a feature, characteristic, mark, or trait. The sense extends from concrete marks on an object to more abstract attributes describing people, phenomena, texts, or data.

In everyday language, piirteistä is used when discussing what can be inferred or described based on certain features. The phrase is commonly found in sentences like “piirteistä voidaan päätellä…” (from the features one can deduce…) or “piirteistä riippuen…” (depending on the features). Its use signals a basis in observable traits or distinguishing marks rather than a general label of all features.

In scientific and descriptive contexts, piirteistä often appears in fields such as linguistics, psychology, biology, and archaeology, where researchers describe data or specimens by referring to their piirteet (features) and then make inferences “piirteistä.” For example, a study might conclude something on the basis of detected piirteistä, or discuss variations in piirteistä between groups.

Etymologically, piirre derives from the root piirt-, related to drawing or marking; the word historically referred to marks and lines and later extended to notes about distinguishing attributes. Related terms include piirteet (nominative plural) and piirros (drawing), which share the same stem. See also phrases like piirteiden perusteella and piirteistä päätellen, which express reasoning or judgment based on features.
