What term describes something that is very profitable?

The term "lucrative" specifically refers to something that yields a significant amount of profit or financial gain. This word is often used in business contexts to describe ventures, investments, or opportunities that are particularly rewarding in terms of generating income or returns.

The other terms, while related to the positive attributes of a financial situation, do not convey the same level of emphasis on profitability as "lucrative." For instance, "beneficial" often refers to anything that results in a positive outcome or advantage, not necessarily linked to profit margins. "Advantageous" similarly indicates a favorable position but lacks the direct financial connotation. "Profitable" does describe something that generates profit, but "lucrative" has a stronger implication of being highly profitable, making it the most precise choice in this context.
