And, or, but. Those are the most common.
conjuctions
The other name that we can use for conjunctions is CONNECTORS, ..they connect nouns, adjectives, sentences...etc.
You can combine two or more simple sentences by using conjuctions. Except for very short sentences, you should put a comma before some conjuctions, which are called coordinating conjunctions.They are :forandnorbutoryetso(the mnemonic is fanboys).The subordinating conjunctions allow one independent clause to modify another.They include :afteralthoughasas ifas long asas thoughbecausebeforeeven ifeven thoughifif onlyin order thatnow thatoncerather thansinceso thatthanthatthoughtillunlessuntilwhenwheneverwherewhereaswhereverwhile

The three conjunctions are coordinating conjunctions, subordinating conjunctions, and correlative conjunctions. Coordinating conjunctions join words, phrases, or independent clauses of equal importance. Subordinating conjunctions introduce dependent clauses that cannot stand alone as complete sentences. Correlative conjunctions work in pairs to connect words, phrases, or clauses with equal weight.
A compound sentence is a sentence that contains two independent clauses joined by a coordinating conjunction (such as "and," "but," or "or"). Each clause in a compound sentence could stand alone as a complete sentence.
I will drive to the store, but you can also walk there if you prefer. She is tired, so she is going to bed early tonight. I would like some ice cream, and I want a cookie too. He studied hard for the test; consequently, he got an A grade.

correlative conjuctions
Conjunctions are important because they help connect words, phrases, and clauses in a sentence to show the relationship between them. They contribute to the coherence and flow of a sentence, allowing for more complex and varied sentence structures. Without conjunctions, writing and speech may sound stilted or disjointed.
A run-on sentence is when two independent clauses (i.e. complete sentences) are joined with no conjunction or punctuation.Example : "He tried medication he did not like the way it made him feel."(needs a period or a conjunction such as "and" or "but")Example : "We were leaving the house the door had to be locked."(a period, or the word "so" after house)* A common misconception is that the run-on means using many multiple clauses and conjuctions, of a long or twisted construction. But this is a style error, not a run-on sentence.
