proporcionally

Proporcionally is a nonstandard English adverb that is sometimes encountered as a misspelling or coinage. In standard usage, the corresponding adverb is proportionally, which describes a relationship in which a quantity changes in direct proportion to another.

Etymology and usage context: The form appears to be built from the noun proportion with the suffix -ally, similar to the formation of proportionally. However, major dictionaries do not recognize proporcionally as a correct variant in English, and it is generally considered incorrect or nonstandard. It may appear in informal writing, non-native texts, or typographical errors, where the intended meaning is likely to be “in proportion” or “in a proportional manner.”

Distinctions and guidance: Proportionally (adverb) conveys a direct, mathematical relationship where one quantity scales with another. Proportionately (adverb) emphasizes a corresponding degree or fairness in distribution, and can carry nuance of appropriateness or balance. In mathematical writing, prefer proportionally or use direct variation phrases such as “y varies proportionally with x” or “y ∝ x.” If encountered as proporcionally, interpret it as a likely misspelling of proportionally unless the author explicitly defines a new or context-specific meaning.

Summary: Proporcionally is not standard English. The correct and widely accepted term is proportionally, used to describe relationships where one quantity changes in direct proportion to another.
