When expressing a decision or an action, it is common to use the phrase "agreed to do." However, there are various synonyms that can be used to diversify your language and avoid repetition. One of the simplest synonyms is "accepted," which shows agreement without specifying the context. If you want to emphasize the commitment, you can use "committed to" or "pledged to," indicating a strong determination to fulfill the task. Other synonyms such as "consented to," "concurred," or "acquiesced" imply a more passive agreement, indicating that someone is approving or allowing something without showing enthusiasm or initiative. Whatever synonym you choose, make sure that it fits the tone and context of your communication.
