When it comes to describing the act of nibbling, there are many synonyms to choose from. Some words that could be used instead of "more nibbled" include "chewed," "gnawed," "munched," and "pecked." Each of these words conveys a slightly different image of how the food is being consumed. For instance, "chewed" suggests a slow, deliberate mastication process, whereas "munched" implies a more hurried or casual style of eating. "Gnawed" has a sharper, more aggressive connotation, while "pecked" might be used to describe the delicate, cautious nibbling of a bird. Ultimately, the choice of synonym will depend on the desired tone and context of the sentence.
