They backup (back up)

One of the most common mistakes in English grammar is the incorrect usage of the phrase "back up." Many people often make the error of spelling it as one word - "backup" - when in reality, it should be written as two separate words - "back up." Understanding the distinction between the verb and the noun form of this phrase is essential for clear and accurate communication.

The Verb: Back Up
