Loneliness refers to a feeling of depression resulting from being alone or from having no companions. It commonly describes the condition or state of being alone or having no companions, the state of being unfrequented or devoid of human activity (of a place or time), and a desire to be alone; disposition to solitude, which gives the term a broader and more practical sense than a single short definition would suggest. Taken together, these meanings present Loneliness as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Loneliness therefore works well as a quotation category because it can hold direct statements about the subject, figurative uses that borrow its meaning, and broader reflections that stay anchored to the same central idea. Loneliness is not limited to a single rigid definition in ordinary language, and that wider range is part of what makes the category useful for grouping related material without losing the term's main sense. When used as a theme, Loneliness can support serious, reflective, argumentative, or even playful quotations, provided the wording still connects back to the core idea described by the source definitions.
