Etymology and form. Abate derives from Old French abat-, abattre, meaning to fell or strike down, from a- “down” + battre “to beat.” The sense “to reduce in amount or intensity” developed in English over time and is now the most common usage in everyday and technical language. The related noun abatement covers the processes and results of abating, as in tax abatement, nuisance abatement, or the abatement of a lawsuit under certain circumstances.

Usage notes. The term is more common in formal, legal, regulatory, and technical writing. In everyday speech, simpler synonyms such as lessen, reduce, or diminish are often preferred. Abatement phrases frequently appear in discussions of environmental policy, urban planning, and tax policy.
