Most capilliform refers to a shape that is thin and hair-like. Some synonyms for this term that can be used interchangeably include slender, threadlike, filiform, and wiry. These words describe something that is long, narrow, and resembling a thread or a wire. Other synonyms include delicate, fine, and thin, which also describe something that is incredibly narrow and delicate. The words spindly and skinny could also be used to describe something that is most capilliform, but both these words have a slightly negative connotation and should be used with caution. All these synonyms can be used to provide a more detailed and nuanced description of an object, animal, or plant that has a capilliform shape.
