When you want to describe something that is almost exact, there are several synonyms you can use. For instance, you could say "nearly precise," "almost accurate," or "virtually flawless." "Close to being exact" is another option, as is "almost dead-on" or "nearly spot-on." Additionally, you could say "almost verbatim," "almost identical," or "nearly the same." Other possible synonyms include "almost perfect," "almost identical," and "almost exactitude." When you swap out the phrase "nearly exact" for one of these alternatives, you can lend more nuance and depth to your writing, making it more descriptive and compelling.
