The term "platelike" is often used to describe an object or shape that is large and flat. However, there are several different synonyms that can accurately convey this meaning. For instance, terms like "plate-like," "flattened," "disc-shaped," and "pancake-like" all describe objects that have a broad, flattened structure. Other relevant synonyms might include "wafer-thin," "planar," "sheet-like," or "slab-like," which can all describe objects with a broad and relatively thin shape. Regardless of the specific synonym used, these terms all convey a sense of largeness and flatness that accurately describes objects that are "platelike".
