Conjunctions - A conjunction is true when all of its conjuncts are true. - Most often this uses “and” as the linking word. - They can also use: “Although” “Even though” “Moreover” “Nevertheless” “Plus” Example: 1. I had both a peanut butter sandwich and a soft drink for lunch. - it contains these statements: I had a peanut butter sandwich for lunch. I had a soft drink for lunch. Note: - sometimes ʻ and ʼ is used to indicate a causal relation between two events and not just that two events occurred. Example: 1. I ate a big dinner and then I felt stuffed.
