What are the most common grammatical errors in English writing?.

Common grammatical errors in English writing often include:

1. Subject-Verb Agreement Errors: Ensuring that subjects and verbs agree in number and tense is crucial. For example, 'She go to the store' should be 'She goes to the store.'
2. Misplaced Commas: Incorrect comma placement can change the meaning of a sentence, such as in 'Let's eat, Grandma' versus 'Let's eat Grandma.'
3. Run-On Sentences: These occur when two independent clauses are improperly joined without punctuation. Example: 'I love writing I do it every day' should be 'I love writing; I do it every day.'
4. Incorrect Tense Usage: Using the wrong verb tense can confuse readers. An example is saying 'He goes to the store yesterday' instead of 'He went to the store yesterday.'
5. Pronoun-Antecedent Agreement: Pronouns must agree in number and gender with their antecedents. For instance, 'Everyone should bring their own lunch' is often deemed incorrect; 'his or her' is more precise, though 'their' is accepted in modern usage.
6. Dangling Modifiers: These occur when a modifier is not clearly connected to the word it modifies, leading to confusion. For example, 'Running down the street, the tree fell' incorrectly suggests the tree was running.
