What term describes a person who lives by begging?

The term "mendicant" specifically refers to a person who relies on begging as their primary means of support. This word has its roots in the Latin term "mendicantem," meaning "to beg." Historically, mendicants were often associated with certain religious orders that renounce material wealth and practice poverty, depending on the generosity of others for sustenance. Therefore, the term is most relevant and apt for describing someone who lives by begging.

In contrast, the other choices do not convey the same meaning. "Jocose" refers to a playful or jesting manner, which is unrelated to the act of begging. "Inveterate" describes something that is firmly established and unlikely to change, often used in contexts like habits or patterns of behavior, rather than specifically indicating a lifestyle of begging. "Minatory," on the other hand, relates to threats or intimidation, which does not correlate with the concept of living by begging. Each of these terms functions within different contexts entirely, further underscoring the appropriateness of "mendicant" as the answer.
