Etymology: The French noun "abattement" comes from the verb "abattre," meaning "to knock down" or "to beat down," itself built from "a-" (to) and "battre" (to beat), so its underlying sense is physical: a blow that brings something low. From that came the notion of a lowering or reduction, and French used the noun for a decline in strength, spirits, or value. The tax sense developed in French public finance, where an abattement is a fixed amount or percentage subtracted from a taxable base before tax is calculated, so that only the remainder is taxed. The word has stayed in French usage rather than passing into English, so it is the kind of term you meet in tax guidance, property law, or cross-border finance, where English speakers often borrow it untranslated. Its meaning is precise: the reduction is applied to the base before the rate is applied, which is what separates it from a simple discount or a credit against the final tax bill.
