The antonym for ambitious is unambitious. An ambitious person is someone who has a strong desire to achieve success, power, or wealth. On the other hand, an unambitious person lacks this strong desire and is often content with their current situation without striving for more.
For example, an ambitious individual might aim to climb the corporate ladder quickly, while an unambitious person might prefer to stay in a comfortable position without seeking promotions or additional responsibilities.
Understanding these terms can help in describing people’s attitudes and motivations in various contexts, such as in the workplace or personal life.
