Definition

Noun: 1. A type of marine mollusk: A primitive, elongated, bilaterally symmetrical marine mollusk having a mantle covered with eight overlapping calcareous plates or shells. 2. A garment from ancient Greece: A form of tunic, typically made of wool or linen, worn by both men and women in ancient Greece.

Examples

1. Marine mollusk:
   • We found a chiton clinging to the rocks in the tidal pool.
   • The chiton's eight protective plates allow it to curl into a ball when dislodged.
2. Ancient Greek garment:
   • The statue depicts a woman wearing a draped chiton.
   • A simple woolen chiton was common everyday attire for ancient Greeks.

Advanced Usage

• In marine biology, the class Polyplacophora, to which chitons belong, is characterized by this distinctive eight-plated shell structure.
• In historical contexts, the Doric chiton was a simpler, heavier style, while the Ionic chiton was lighter, often made of linen, and fastened with multiple brooches.

Variants and Related Words

• Polyplacophoran (n): The scientific term for a chiton.
• Tunic (n): A general term for a simple garment reaching from the shoulders to somewhere between the hips and knees; the chiton is a specific type of tunic.

Synonyms

1. For the mollusk: Sea cradle, coat-of-mail shell (informal names based on its appearance).
2. For the garment: Tunic, robe.

Notes on Different Meanings

The two meanings of chiton are homographs (spelled the same) but are entirely unrelated in origin and refer to completely different things—one is a zoological term, the other a historical/textile term. Context always makes clear which is intended.
