passion
A very strong love or excitement for something you care about.
Passion is intense enthusiasm or love for something that drives you to pursue it with energy and dedication. When you have passion for music, you want to practice your instrument every day, learn new techniques, and lose track of time while playing. A passionate reader devours stories late into the night, hungry for more, going far beyond assigned books.
Passion gives people the fuel to keep going when things get difficult. A scientist with passion for discovery will run experiment after experiment, even when most of them fail. An athlete with passion for their sport will practice in the rain and push through exhaustion. Passion makes hard work feel meaningful rather than boring.
The word can also describe strong emotions or feelings about anything. Someone might speak with passion about protecting endangered animals or argue with passion about which superhero is strongest. In historical contexts, passion sometimes refers to intense suffering, especially in religious texts describing the final days of Jesus Christ.
Passion shows up in consistent action, working to improve, and caring deeply even when no one's watching. It's not merely saying you like something.
