Do you want to stop saying “He’s good” and “She works well” in professional settings?
In business English, precision is power. Using advanced, specific adjectives not only makes you sound more fluent but also helps you write better performance reviews, ace job interviews, and give meaningful compliments.
Here are 8 powerful adjectives you can use to describe colleagues, employees, and yourself — like a manager.
1. Reliable /riˈlaɪəbəl/

This comes from the verb to rely on — to depend on someone.

At Work:
- My assistant is extremely reliable; if she says the report will be ready by 3 PM, it will be.
- He’s a reliable team member — you can always count on him in a crisis.

Beyond People: You can also describe things: a reliable car, a reliable service, reliable data.
