The quality or habit of giving in to other people — the noun for being submissive. It names a trait or a pattern, not a single action: her submissiveness surprised everyone; he was raised to value submissiveness. Because it is a -ness noun, it is uncountable: say 'her submissiveness', not 'a submissiveness' or 'submissivenesses'. Like the adjective, it usually carries a mild criticism or at least a worry. Writers use it when someone gives in too easily, too often, or to someone who does not deserve it — so it shows up a lot in writing about abusive relationships, strict workplaces, and cultures that expect women or juniors to stay quiet. It is also a plain technical term in animal behaviour (submissiveness in a pack) and in psychology, where it names a measurable personality dimension with no insult intended. And in writing about certain relationships, submissiveness is a role people choose, which flips it from weakness to consent. This is a formal, essay-and-textbook word; in speech people say things like 'he's too soft' or 'she never says no'.
