dedication
Strong commitment to keep working toward something important.
Dedication means unwavering commitment to a goal, person, or cause, even when it's difficult. When a musician practices scales for hours every day, that's dedication. When a student keeps working on a challenging science project through multiple failed attempts, that's dedication too.
Dedication involves showing up consistently, putting in effort when you don't feel like it, and pushing through frustration. A dedicated athlete doesn't skip practice when it's raining. A dedicated friend doesn't disappear when things get complicated.
You can also dedicate something to someone, which means creating it in their honor or memory. Authors often dedicate books to people who supported them. A community might dedicate a park to a beloved teacher, naming it after her to remember her contributions.
Dedication is devoting yourself fully to something worthwhile. When you dedicate yourself to learning piano, improving at chess, or helping your younger sibling with reading, you're making a promise to stick with it through the boring parts, the hard parts, and the moments when progress feels impossible.
