Silence refers to the absence of any sound. It commonly describes the act of refraining from speaking, form of meditative worship practiced by the Society of Friends (Quakers); meeting for worship, and to make (someone or something) silent, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to to repress the expression of something, to suppress criticism, etc, and to block gene expression, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Silence 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. Additional shades of meaning include murder and be silent, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term. Silence 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. Silence 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.
