When you want to describe something that isn't exact, the word "imprecisely" comes to mind. But sometimes, it's nice to switch things up and use a synonymous word. Here are a few options: vaguely, inaccurately, loosely, approximately, indistinctly, hazily, ambiguously, uncertainly, indefinably, and inexplicitly. Each of these synonyms can be used in place of "imprecisely" to give a slightly different nuance or tone to your writing. For example, "vaguely" and "indistinctly" suggest a lack of clarity, while "approximately" and "loosely" indicate an approximation or approximation. So, choose your synonym wisely depending on what impression you want to create in the minds of your readers.
