  • You’re going to enjoy this lesson.

  • Your welcome.

  • You’re welcome.

Their vs There vs They’re

These three words sound the same but have different meanings.

  • Their shows possession.

Examples:

  • The keys are over there.

Who and whom are often confused.

Subject-Verb Agreement Errors

Another common mistake occurs when the subject and verb do not agree in number.

Examples:

  • I saw a cat in the garden.
  • The cat was sleeping under the tree.

Incorrect Use of Prepositions

Prepositions such as in, on, and at are often used incorrectly by English learners.
