If you always do what you’re told, you can be described as obedient. Authority figures love to have obedient followers.
When you realize that the word obedient comes from a Latin word meaning “to obey,” it’s easy to remember what obedient means. Use obedient to describe someone who knows the rules, toes the line, and follows instructions. The word can refer to people (an obedient student), a group (obedient citizens), or even animals (an obedient dog).
