A dedication is a promise or statement of commitment to something or someone.
When we dedicate ourselves to something, it's like giving our time, energy, and attention to it. We do this often in personal relationships - for example, if you say "I dedicate my life to my family," that means you're putting their needs above your own and making sure they come first. But dedication can also be a promise we make to a cause or activity, like volunteering at a charity or training for a marathon.
