A sentence is grammatically correct when there are no errors in grammar. To determine whether a sentence is correct or incorrect, we must first determine the subject-verb agreement.
Sentence 1: "She and I" are correct because the position is subject. ✅
Sentence 2: "Her and me" are incorrect. It must be the object of the sentence and not the subject. ❌
Sentence 3: "She and I" are correct because the position is subject. ✅
Second, let's focus on the sentence 1 and 3 only. There is a different use of step by step or step-by-step
- Adjective describes noun/pronouns
- Adverb describes verbs, adjectives, or other adverb.
