Other forms: dedicatedly
When you are dedicated to something, you are devoted to a cause or ideal, like dedicated volunteers at the animal shelter who show up even in snowstorms and on holidays.
Dedicated contains the root word dedicate, meaning "devoted to one's aims or vocation," like a dedicated staff of workers who work extremely hard. It can also mean "set aside for a specific purpose," like a dedicated desk where family members place their keys, the mail and notes to one another — don't throw your coat on top of that desk or throw those items in a drawer.
