Only a handful of adjectives start with Z, and most people know just two or three. Adjectives that start with Z bring zany, zealous, and zesty for everyday talk, and zoological, zygotic, and zymotic for science writing. Some describe how a person looks or acts, and the rest name a shape, a texture, or a mineral. This small group is worth using with care.
