4.3 Plural Form “Dice”

Traditionally, dice is the plural form of die in gaming.
In casual speech, dice is increasingly used as both singular and plural (e.g., “I lost a dice”).
In formal/academic contexts, die for singular and dice for plural are preferred.

Examples:

“Roll a die to start the game.”
“She threw two dice.”
Informal: “I lost a dice.” (increasingly common but less formal)

4.4 Plural Form “Dies”

Used mainly in technical contexts, such as metalworking, jewelry, or electronics.

Refers to multiple tools, molds, or devices.

Examples:

“The technician replaced the worn dies.”
“Different dies produce different shapes.”

4.5 Historical Evolution and Etymology

Origin: From Latin datum (meaning “something given”), which passed into Old French as dé (singular) and dées (plural).
In English, die entered as the singular, with dice as the plural.
Over time, dice also began to be used as a singular noun in informal speech.
The plural dies in technical contexts likely developed independently, following the typical -s pluralization pattern.
