Which term signifies a state of being troubled or mourning?

The term that signifies a state of being troubled or mourning is "lachrymose." This word is derived from the Latin "lacrima," which means "tear," and is typically used to describe someone who is tearful or prone to weeping. It evokes a sense of sorrow or grief, often in a deeply emotional context. When someone is described as lachrymose, it implies that they are experiencing intense feelings of sadness or melancholia, which aligns with the idea of mourning or being troubled.

Each of these terms has its own distinct meaning, differentiating them from the emotional connotation inherent in "lachrymose."
