vertentes

Vertentes is the plural form of vertente in Portuguese and is used in several senses related to geography, hydrology, and figurative language. Literally, vertente refers to the side or slope of a relief feature such as a hill or mountain, and vertentes denotes the different faces or orientations of such a feature, often described by compass direction (for example, a vertente norte or vertente sul). In hydrological and geomorphological contexts, the term can describe portions of a terrain that contribute drainage to a particular river system, i.e., sub-areas within a drainage basin that share common flow directions. Figuratively, vertente is used to indicate an aspect or facet of a topic, issue, or field of study, similar to terms like aspect or dimension. The word also appears in toponyms and administrative names in Portuguese-speaking regions, where it may refer to a locality, district, or geographic feature named for its slope or orientation. While not tied to a single, widely standardized definition, vertentes generally conveys ideas of direction, side, and facet in both physical and metaphorical senses.
