Genuine means real, authentic, or sincere. A genuine diamond is a real diamond, not a piece of glass or cubic zirconia made to look like one. A genuine antique is actually old and valuable, not a modern reproduction. When you buy genuine leather, you're getting actual animal hide, not vinyl or plastic.

The word also describes people and emotions that are honest and true. When someone shows genuine interest in your hobby, they really care about what you're saying and actively engage with it. A genuine smile reaches your eyes, while a fake smile is just your mouth moving. A genuine friend supports you during difficult times, whether or not it's convenient or fun.

You can spot the difference between genuine and fake by paying attention. Genuine enthusiasm feels warm and natural. Genuine concern shows itself through actions, not just words. When someone offers a genuine apology, they truly feel sorry and want to make things right, seeking to repair the relationship rather than simply avoid consequences.

The opposite of genuine is counterfeit, fake, phony, or insincere. Being genuine yourself means saying what you really think (in a kind way) and showing your true feelings rather than putting on an act to impress others.
