The word "submissive" refers to someone who is compliant, docile, and obedient. Its antonyms are assertive, confident, and self-assured. An assertive person is one who is confident and forceful in expressing their opinions and needs, while a confident person is self-assured and has a strong belief in their abilities. A self-assured person, on the other hand, is someone who is comfortable with themselves and their abilities, and is not easily swayed by the opinions of others. These antonyms for submissive are characteristics that make one stand up for themselves and assert their independence, rather than following others blindly.
