Usage Note

Oneroso is a formal adjective describing something that imposes a heavy obligation or cost — a tax, a contract clause, or a legal duty. In civil law, a contratto oneroso is one where both parties exchange consideration, as opposed to a contratto gratuito. It is not used for physical heaviness; use pesante for that.

Examples

"Le condizioni del contratto sono molto onerose."

Natural Translation

The contract conditions are very burdensome.
