An admirer is someone who respects, appreciates, or looks up to another person. When you're an admirer of someone, you notice their talents, character, or achievements and feel genuine appreciation for them. You might be an admirer of a favorite author whose books inspire you, or an admirer of a scientist whose discoveries changed the world.

The word often suggests viewing someone from a distance with respect and appreciation. A young basketball player might be an admirer of a professional athlete, studying their techniques and dedication. A student interested in marine biology might be an admirer of Jacques Cousteau, even though he lived decades ago.

Sometimes admirer means someone who has romantic feelings for another person, though this usage is a bit old-fashioned. In classic novels, a character might have a “secret admirer” who leaves anonymous notes.

You can also be an admirer of things rather than people. Someone might be an admirer of classical music, Japanese gardens, or Renaissance art. This means they appreciate these things deeply and enjoy learning more about them. Being an admirer shows you're paying attention to excellence and quality in the world around you.
