A conjunction is a word that joins two other words that are the same kind as each other (two nouns, two verbs, two adjectives, etc.) or that joins two groups of words.
The word "or" is a conjunction because it joins two other words: Tell me if you see a red or blue car.
The word "that" is sometimes a conjunction, as in "I think that you are right."
