What Are One-Word Descriptions of People?

"Nervous," "thoughtful" and "respectful" are examples of one-word adjectives that describe people. In the sentence, "John was nervous before the big game," for instance, the word nervous is an adjective used to describe how John felt right before the big game. In contrast, someone could describe John as being "anxious," "excited" or "elated" before the big game. Adjectives include positive and negative characteristics.
