Definition & Meaning of "correction fluid"in English

What is "correction fluid"?

Correction fluid is a liquid used to cover up mistakes made with ink or pen on paper. It typically comes in a small bottle with a brush or sponge applicator, allowing users to apply a thin layer of white fluid over the error. Once it dries, the fluid creates a blank area where the mistake was, allowing the correct text to be written over it. Correction fluid is commonly used for fixing errors in documents, notes, or forms. It provides a smooth surface that can be written on once dry, making it a useful tool for ensuring neat and accurate work.
