Connotation refers to the emotional or cultural associations that a word carries beyond its literal meaning, or denotation. These associations can be positive, negative, or neutral, influencing how we perceive and interpret language. For example, the word "home" connotes warmth, safety, and comfort, while "house" is more neutral and simply refers to a physical structure. Understanding connotation is essential for effective communication, as it can shape the tone and impact of words.
