Which word means to praise highly?

The word "extol" means to praise highly or to enthusiastically commend someone or something. It is often used in contexts where there is a strong expression of approval or admiration. For example, one might extol the virtues of a political leader, praising their achievements and contributions in a prominent and positive manner.

In contrast, "effusive" refers to a display of unrestrained emotion, often in praise, but it does not specifically mean to praise itself. "Prevarication" relates to the act of lying or being deliberately ambiguous, thus having no connection to praise. "Benign" describes something that is gentle or harmless, which also does not align with the idea of high praise. Therefore, the choice of "extol" is appropriate as it captures the essence of giving high praise effectively.
