fija

Fija is the feminine form of the Spanish adjective fijo, meaning fixed, immovable, or permanent. It derives from the Latin fixus and is used to describe things that do not change or are established by definition, policy, or design. The masculine counterpart is fijo, and the two forms agree with the gender of the noun they modify.

Usage and examples: Fija appears in a range of neutral, technical, and everyday expressions. Common examples include tarifa fija (a fixed rate), precio fijo (a fixed price), posición fija (a fixed position), and tasa fija (a fixed tax or rate). In contrast to variable or móvil terms, fija emphasizes stability or constancy. Because gender agreement matters in Spanish, fija is appropriate whenever the noun it modifies is feminine, such as tarifa, tasa, posición, or política fija (a fixed policy).

Contexts and nuance: In business, engineering, and economics, fija is widely used to indicate unchanging values or arrangements. It can also describe decisions or standards that are intended to remain constant over time. While the concept of fixity can apply broadly, the vocabulary tends to pair with specific feminine nouns, with fijo or variables used for masculine or variable concepts.

Cross-language notes: Similar forms exist in other Romance languages, such as Portuguese fixa and Italian fissa, reflecting the same root meaning of steadiness or permanence. In Spanish, fija is primarily an adjective, with its meaning understood through context; standalone use as a noun is uncommon in standard usage.
