When trying to write more concise and effective sentences, it's important to have a variety of phrases that can replace commonly used ones. For instance, "with purpose that" could be substituted with phrases like "aiming to," "intending to," "with the goal of," or "with the intention of." All of these alternatives convey the same idea while adding variety and interest to your writing. Other phrases to consider might include "focused on," "directed toward," or "driven by." By using these kinds of synonyms, you can make your writing more dynamic and engaging, which can help keep your readers interested and engaged.
