Plural of Die
“Die” has a sense-dependent plural. A small marked gaming cube normally has the plural “dice.” A die used for cutting, shaping, stamping, molding, threading, or related technical purposes has the plural “dies.” The two plurals are not interchangeable spellings for the same sense.
Use “dice” for more than one gaming die; use “dies” for the tool, mold, shaping, stamping, and related technical noun senses.
