* Sentence structure: While subject pronouns typically come before the verb in a declarative sentence (a statement), there are other sentence structures where this isn't the case. For example:
* Questions: In questions, the subject often comes *after* the verb: "Do *you* like pizza?"
* Inverted sentences: Some sentences intentionally switch the word order for emphasis: "*He* is the one I trust."
* Imperative sentences: Imperative sentences (commands) often omit the subject pronoun, implying "you": "Go to the store."
* Emphasis: Sometimes, even in declarative sentences, a subject pronoun can be moved for emphasis: "I am the one who did it!"
Key Point: The placement of a subject pronoun depends on the sentence structure and intended emphasis. While they often begin a sentence, it's not a hard and fast rule.
