Also means

burdensome

Usage Note

Oneroso is a formal, often legal or economic word meaning involving a heavy financial or administrative burden — not merely 'annoying'. In contract law, a contrato oneroso is one where both parties exchange obligations of value, as opposed to a contrato gratuito. In everyday prose it most often describes taxes, fees, or conditions felt to be excessively heavy.

Examples

"Las condiciones del préstamo resultaron onerosas."

Natural Translation

The loan conditions turned out to be onerous.
