Which adjective means abounding in or given to pompous moralizing?

The word "sententious" is derived from a term that suggests an inclination toward moralizing or delivering opinions in a pompous or self-righteous manner. This adjective is often used to describe statements or people that are overly moralizing, preachy, or smugly philosophical, often delivering their messages with a certain self-importance. In contrast to the other choices, which have unrelated meanings—such as "saturnine" referring to a gloomy disposition, "sanguine" indicating a cheerful or optimistic nature, and "recumbent" meaning lying down or reclining—"sententious" specifically captures the notion of someone who is prone to conveying moral lessons, often with an air of superiority. This makes it the most fitting descriptor in the context of being "abounding in or given to pompous moralizing."
