Grammar Patterns

autonomous + noun (person)

be autonomous

autonomous needs evidence of self-direction, not just physical proximity.

    very close meaning; preferred when stressing the ability to make laws

Antonyms

Usage Note

Distinguish from sense 1 (human) and sense 2 (political): nothing here is about personal or political freedom.

Synonym discussion

Sense: adjective/1

All four words describe someone who can act without leaning on others, but each fits a different angle. 'Independent' is the everyday word — a teenager who pays her own rent is independent. 'Autonomous' sounds more formal and adds the idea of having the right and the ability to choose one's own rules; an autonomous learner doesn't just study alone, she decides what and how to study. 'Self-reliant' focuses on coping without help, especially in practical matters: a self-reliant hiker carries her own gear and food. 'Self-directed' is narrower again, used most often for learners or workers who set their own goals: a self-directed researcher picks her own questions. So you might say, 'Mei is an independent student' (lives alone), 'an autonomous student' (chooses her own subjects), or 'a self-directed student' (drives her own learning project).

Etymology

GreekLatinEnglish

Built from the Greek roots 'auto-' (self) and 'nomos' (law or rule), so the literal idea is 'making one's own laws'. It entered English in the seventeenth century, first describing Greek city-states that ran themselves. Over time it spread from politics to people (a person who chooses for herself) and, much later in the twentieth and twenty-first centuries, to machines and software that can operate without human control.
