measurably

Measurably is an English adverb meaning to a degree that can be measured or quantified; in a way that can be assessed with a metric. It is typically used to indicate that the extent of a property or effect can be observed and expressed numerically, as in phrases like measurably faster or measurably higher yields. It derives from the adjective measurable and the standard adverbial suffix -ly.

Etymology and formation: the word is formed by adding -ly to measurable, the adjective describing something that can be measured. Its usage centers on quantification and empirical assessment rather than subjective impression.

Usage and nuance: measurably is common in scientific, technical, business, and policy writing where outcomes are described in terms of measurable effects. Examples include measurably better performance, measurably lower costs, or measurably increased accuracy. It does not by itself imply statistical significance; rather, it signals that a metric exists and can be reported. In some contexts, writers distinguish measurably from statistically significant, using the former to emphasize the existence of a metric and the latter to imply a formal statistical result.

Related terms: measurable (adjective), measurement, quantifiable, and quantitatively. Measurably complements these terms by describing the manner in which a property is observed or reported, rather than the property itself or the act of measuring.
