When it comes to chewing, the word "masticating" is often used. However, there are many other synonyms that can be used to describe the act of chewing. Some possible options include grinding, gnawing, biting, chomping, munching, and crunching. Each of these words conveys a slightly different nuance, with some suggesting a more forceful or rapid chewing motion and others emphasizing a slower, more deliberate approach. Depending on the context and the desired tone, any one of these alternatives might make a suitable substitute for "more masticating".
