Answer:
Main clause
Step-by-step explanation:
A main clause, also called an independent clause, is the essential component in a sentence because every sentence should have one (and it can have more than one too). This type of clause may be next to other clauses, however, it can also stand alone because its meaning is complete, in other words, it expresses a complete thought. Here are some examples of sentences, the main clause is underlined:
Before my first date with Tom, I decided to dye my hair blue.
She was craving for a little piece of cake, but she remained quiet.
Mary is a dog person and I am a cat person.
When there are more than one main clause in a sentence, it is a compound sentence.
