desfavorables

Desfavorables is the plural form of the Spanish adjective desfavorable, meaning not favorable, adverse, or disadvantageous. The term is used to describe factors, conditions, or outcomes that hinder progress, increase risk, or reduce desirability. It is applied across domains such as economics, meteorology, medicine, and social sciences to characterize environments, forecasts, or results that are less than optimal.

Linguistic and semantic notes: desfavorable derives from the prefix des- (negation) added to favor, with the suffix -able indicating suitability. In practice, desfavorable is often used with nouns such as condiciones, escenarios, resultados, or efectos to express an adverse quality or impact. The plural desfavorables refers to multiple unfavorable items or factors. A related noun form is desfavorabilidad, which denotes the general quality of being unfavorable or the degree of discouragement or unlikelihood.

Common contexts and usage: in business or economics, one may speak of condiciones desfavorables for investment or escenarios desfavorables in a forecast. In climatology or agriculture, condiciones meteorológicas desfavorables describe weather conditions that adversely affect crops. In pharmacovigilance, one may refer to efectos desfavorables, though more common terms include efectos adversos.

See also: desfavorable (adjective), desfavorabilidad (noun), condiciones adversas, efectos adversos, escenarios desfavorables, inversiones desfavorables.

Note: While equivalent in many contexts to “unfavorable” or “adverse” in English, usage in Spanish varies by field and region, and some domains prefer synonyms such as adversos or perjudiciales.
