The word "mummylike" is commonly used to describe something that resembles or has attributes similar to that of a mummy. However, there are several other synonyms that can be used in place of this word, such as desiccated, shriveled, withered, emaciated, and shrunken. These synonyms all suggest an appearance of drying or dehydration, which is commonly associated with mummies. Additionally, other descriptive words can be used to convey a similar meaning, such as ancient, preserved, or fossilized. Using these different synonyms can help to avoid repetition in writing and provide a more varied vocabulary to convey meaning.
