Definition
"Abrasive" describes something that causes friction or irritation, either physically or emotionally. It can refer to a rough material used for grinding or polishing, or to a personality that is irritating and unpleasant. Think of sandpaper rubbing against wood, or a person who is overly critical and insensitive. It suggests a lack of smoothness or tact, often leading to discomfort or conflict. Unlike something merely annoying, "abrasive" implies a quality that wears down or damages. It is an unpleasant personality trait.
