efektów

Efekt is a masculine Polish noun meaning effect, result, or outcome. The form efektów is its genitive plural, used to denote "of effects" or to express quantity or containment where the genitive is required. As a borrowed word, its etymology traces from Latin effectus, through German Effekt and French effet, entering Polish in the modern period.

In usage, efektów appears in contexts such as analysis, description of results, and discussion of medical or scientific phenomena. Examples: W badaniach zaobserwowano wiele efektów. (Many effects were observed in the studies.) Leki mogą powodować różne efekty uboczne, a niektóre efektów? Actually correct: różne efekty uboczne; efekte is plural nominative. To keep with genitive plural: nie wszystkie efektów? A better example: nie wszystkie efektów terapii? This is awkward. A clear example is: Analiza efektów ubocznych obejmuje różne typy reakcji. In many phrases, efekte uboczne is common, and the full genitive phrase would be "efektów ubocznych" (of side effects). The phrase "nie ma efektów" demonstrates genitive plural after negation. In everyday language, efekte uboczne, długofalowe efekty, or krótkotrwałe efekty are typical collocations.

Efektów is also used to distinguish subtler meanings from related terms. Efekt conveys a specific observable result or outcome produced by a cause, often in scientific or technical contexts. Skutek and rezultat are close substitutes; skutek emphasizes consequence or outcome, often with a formal or negative nuance, while rezultat denotes a concrete, measured result of a process. The noun declines as singular efekt, efektem, efekcie and plural efekty, efektów, efektom, efekty, efektami, efektach.

Notes: Polish declension can be summarized as follows for singular: nom efekt, gen efektu, dat efektowi, acc efekt, instr efektem, loc efekcie; plural: nom efekty, gen efektów, dat efektom, acc efekty, instr efektami, loc efektach.
