lesserused

Lesserused is an English adjective meaning used less frequently than something else in a given context. It can describe objects, features, or practices that have lower usage rates compared to more common alternatives.

The term is not widely standardized and may be found primarily in informal writing, design discussions, or niche analyses. In formal writing, authorities commonly recommend more precise phrases such as "infrequently used" or "low-usage."

Common domains for the term include linguistics, where lists of lesserused words identify relatively rare vocabulary; technology and product development, where lesser-used features are sometimes targeted for deprecation or redesign; and transportation planning, where lesser-used routes are evaluated for optimization.

Usage notes: because lesserused is not standard, readers may prefer hyphenation "lesser-used" in some contexts, though many style guides discourage unnecessary hyphenation. When possible, replace with clearer phrasing to avoid ambiguity.
