The phrase "dedicate to" is typically used to describe a commitment to a specific person, cause, or activity. However, there are a variety of synonyms that can be used to convey a similar meaning. For example, you might say that you are "devoted to" a particular hobby or "committed to" a certain goal. Other options include being "loyal to," "passionate about," or "focused on" something. These synonyms all imply a strong sense of dedication or loyalty, but each one may be better suited to a specific context. Ultimately, the choice of synonym will depend on the speaker's intended meaning, as well as the tone and style of the surrounding text.
