Which term describes something that is easy or effortless?

The term that describes something that is easy or effortless is "facile." This word is often used to indicate that a task or situation can be accomplished with minimal difficulty or that something is done with a level of ease that may even suggest a lack of depth or complexity. In contexts such as discussions about skill or performance, "facile" can imply that the effort required is so minimal that it raises questions about sincerity or seriousness.

In this context, the other choices do not convey the same meaning. "Extradite" refers to the process of sending a person back to a jurisdiction to face charges, which is unrelated to the idea of ease. "Garrulous" describes someone who is excessively talkative, often about trivial matters, rather than something that is effortless. "Gibe" refers to a taunt or mocking remark, which also does not relate to ease or lack of effort. Therefore, the correct choice effectively captures the notion of effortless and easy accomplishment.
