Shrew-sized is a term used to describe something very small, such as a tiny object or creature. There are several synonyms that capture this same meaning such as miniature, pint-sized, tiny, small, micro, and minuscule. However, the word shrew can carry negative connotations, so one may want to consider these alternatives when describing something tiny in a more neutral manner. Other synonyms include compact, pocket-sized, bite-sized, nanoscopic, and Lilliputian. Each of these words describes something small and can be used as a substitute for shrew-sized, depending on the context and tone of the sentence.
