What term would you use to describe a persistent tendency towards sadness or mourning?

The term "lachrymose" is derived from the Latin word "lacrima," meaning tear, and it specifically denotes a state of being tearful or weepy, often associated with deep sadness or sorrow. When describing a persistent tendency towards sadness or mourning, "lachrymose" captures this emotional quality effectively, conveying the idea of someone who is prone to tears or a melancholic disposition.

In contrast, "lassitude" refers to a state of physical or mental weariness, which does not inherently imply sadness; it describes a lack of energy or vitality. "Limn" means to depict or describe in painting or words, which is unrelated to emotions or tendencies towards mourning. "Libertine" describes a person who behaves without moral principles or a sense of responsibility, particularly in sexual matters, and does not convey an inclination towards sadness or mourning. Thus, "lachrymose" is the most appropriate choice for describing a consistent tendency towards sadness.
