Mierzalna

Mierzalna is the feminine singular form of the Polish adjective mierzalny, meaning measurable or capable of being measured. It is used to describe nouns that can be quantified or evaluated by a metric. As a grammatical form, mierzalna agrees with feminine singular nouns, for example cecha mierzalna or zmienna mierzalna.

The term derives from miara (measure) with the productive suffix -alny, which marks an attribute. The related forms are mierzalny (masculine) and mierzalne (neuter). In noun form, the abstract noun mierzalność denotes measurability, the quality of being measurable.

In science, research, and quality control, it is common to refer to a cecha mierzalna or zmienna mierzalna, i.e., a feature or variable that can be quantified. In discourse about goals or criteria, mierzalne criteria or mierzalne results are preferred because they support objective assessment. For example: "To cecha mierzalna, którą można zmierzyć za pomocą skali 0–100." and "Wyniki powinny być mierzalne, aby porównać postęp między zespołami." The feminine form is used when the noun it modifies is feminine, e.g., "ta cecha mierzalna została zdefiniowana operacyjnie."
