To readjust means to adjust something again, or to change your position, thinking, or approach after circumstances have changed.

When you've been sitting in one position for a long time and start to feel uncomfortable, you might readjust yourself in your chair to get more comfortable. After returning from a dark movie theater into bright sunlight, your eyes need a moment to readjust to the light. These are physical readjustments.

But readjustment also happens mentally. When you start a new school year with a different teacher who has different rules and expectations, you readjust your behavior and study habits to match. After spending summer vacation staying up late and sleeping in, you have to readjust to your school schedule in September.

Sometimes plans change suddenly, and you need to readjust your thinking. If your team is losing at halftime, you might readjust your strategy for the second half. If you thought a book report would be easy but the book turns out to be more challenging than expected, you readjust how much time you spend on it.

The word suggests flexibility: life rarely goes exactly as planned, and being able to readjust means you can adapt and keep moving forward when things change.
