progressively

Progressively is an English adverb derived from the adjective progressive. It describes a process that unfolds in a series of steps or increases in intensity, scope, or magnitude over time. The sense is often synonymous with gradually or increasingly, but it emphasizes ongoing development rather than a single change. The word is common in formal, scientific, and analytical writing to characterize trends and changes.

Usage examples include describing gradual changes over time, such as “The temperature rose progressively throughout the day,” or “The project faced progressively larger challenges.” In technical writing, progressively can highlight stepwise or accumulative effects, such as dose–response relationships, learning curves, or policy implementations that expand over time.

In grammar, progressively functions as an adverb of manner, modifying verbs or adjectives to indicate how a change occurs. It is often contrasted with abrupt or immediate changes and, to some extent, with gradually. While progressively and gradually can be interchangeable in some contexts, progressively tends to imply a continuing, directional trend rather than merely a slow pace.

Etymology and usage notes: the word is formed from progressive with the adverbial suffix -ly, reflecting English derivation from Latin progressivus. It has widespread usage across English varieties, particularly in prose that aims to describe development or change as it unfolds.
