reductional

Reductional is an adjective derived from reduction, used primarily in technical or scholarly English to describe something related to or resulting from reduction. It involves making something smaller, simpler, or in a more basic form. The suffix -al marks it as an attribute.

In linguistic contexts, reductional describes processes that shorten or weaken phonetic forms, such as vowel reduction or consonant elision, or the general tendency toward less distinct pronunciation under certain conditions. In chemistry, the term is less common; when used, reductional may relate to aspects of reduction reactions—the gain of electrons by a species—though "reductive" is the more standard adjective. In philosophy, psychology, or related fields, reductional approaches or analyses aim to explain complex phenomena in terms of their simpler components, reflecting reductionism.

The word is rarely used in everyday language, and its precise meaning is highly dependent on domain-specific conventions. When encountered, it usually signals a focus on the process or result of reduction, or on a reduced form of something, rather than on the act of reducing itself.

Originates from the noun reduction, with the suffix -al; ultimately from Latin reducere and French réduction.
