I have a few questions about grammar

1, Does a sentence that starts of with "if" an independent sentence or a dependant?
2, Does a sentence that starts of with "in order to" an independent sentence or a dependant?
2, is there a comma before “instead of” and “rather than”?
3, is there a comma before in order to that is not starting a sentence.
plsssss help!!!!!!!

1. It can be either;

"If I were you, " >> dependent clause
"If I were you, I'd study more. " >> independent clause, sentence

2. Same principle as number 1.

2. Not ususally

3, Usually

1. When a sentence starts with "if," it typically signals the beginning of a dependent (or subordinate) clause. A dependent clause cannot stand alone as a complete sentence and relies on another clause to form a complete thought. For example: "If it rains tomorrow" is a dependent clause because it requires another clause to complete the sentence, such as "we will stay indoors."

2. Similarly, a sentence that begins with "in order to" also introduces a dependent clause. The phrase "in order to" indicates purpose or intention and requires a main clause to form a complete sentence. For instance: "In order to pass the exam" is a dependent clause that requires further context, like "I studied diligently."

3. In general, there is no comma before "instead of" and "rather than." These phrases are coordinating conjunctions that function to compare or contrast ideas. However, there might be situations where a comma is required based on the structure and meaning of the sentence. For example: "I prefer tea instead of coffee" does not require a comma because it is a simple comparison. But if you have a list of items, the comma might be necessary, such as: "She likes to read books, watch movies, instead of going to parties."

4. Regarding the phrase "in order to" not at the start of a sentence, it is unlikely to require a comma. Generally, a comma is not used before "in order to" unless it is displaying a pause or emphasizing a certain element in the sentence. For instance, you may use a comma if you want to emphasize the purpose clause: "He went to the store, in order to buy some groceries."

Remember, grammar rules can vary depending on the context and style guidelines you are following. It's always helpful to refer to a reliable grammar resource for more specific rules and examples.
