1. Subject-Verb Agreement: This error occurs when the verb in a sentence does not match the subject in number (singular or plural).
* Example: *The dog bark loudly.* (Incorrect)
* Corrected: *The dog barks loudly.* (Correct)
2. Pronoun Agreement: This error occurs when a pronoun does not agree with its antecedent (the noun or pronoun it refers to) in number, gender, or person.
* Example: *The team celebrated their victory.* (Incorrect)
* Corrected: *The team celebrated its victory.* (Correct)
3. Run-on Sentences: These occur when two or more independent clauses (sentences that can stand alone) are joined together without proper punctuation or conjunction.
* Example: *I went to the store I bought some groceries.* (Incorrect)
* Corrected: *I went to the store, and I bought some groceries.* (Correct)
These are just a few examples of the many sentence errors that can occur. However, they are among the most common and are essential for understanding how to write clear and grammatically correct sentences.
