Submissively is an adverb that describes a person or their behavior as showing obedience, humility, or a willingness to yield or comply with others. It indicates the act of yielding to someone else's authority or wishes in a meek or compliant manner. A person behaving submissively will exhibit signs of deference, often accompanied by lowered social status or power. It suggests a lack of assertion or the willingness to conform to someone else's desires or expectations without resistance.
Someone who acts submissively may display traits such as bowing their head, avoiding eye contact, speaking in a quiet and apologetic manner, complying without question, or accepting orders without voicing dissent. Submissiveness can be seen in personal relationships, social interactions, professional environments, or situations of hierarchy or power imbalance.
It is important to note that the term "submissively" implies a voluntary and conscious choice to behave in such a manner, rather than being forced or compelled.
