"Laciniform" is a unique word that describes something or someone that is shaped like a small jagged or serrated edge. This word can be difficult to find synonyms for, but some viable options include jagged, serrated, notched, saw-toothed, toothed, and crenulated. "Jagged" is a great synonym for laciniform because it paints a vivid picture of a rough and uneven edge. "Serrated" is another great option because it describes a sharp, saw-like edge. "Notched", "toothed", and "saw-toothed" also effectively convey the jagged nature of laciniform. If one is looking for something slightly softer, "crenulated" may work, as it suggests a more wavy or scalloped edge.
