Meaning of Ruby
Definition
Ruby (noun): A ruby is a valuable, usually red gemstone that is a variety of the mineral corundum.
A ruby is known for its rich red color and beauty. It is commonly used in rings, necklaces, earrings, and other jewelry.

The word can also describe a deep red color. For example, someone may describe a fabric as having a ruby color.
Connotative Meaning
Connotation means the feelings, ideas, or associations that a word suggests beyond its basic dictionary meaning.
- Positive tone: Ruby often suggests beauty, luxury, love, wealth, passion, rarity, and elegance.
- Negative tone: The word itself is not normally negative, although it may suggest excessive wealth or extravagance in some contexts.
- Neutral tone: In geology, gemology, or science, ruby can simply identify a type of mineral or gemstone without emotional meaning.
Etymology
- Ruby entered English through Old French rubi.
- Old French rubi came from Medieval Latin rubinus lapis, meaning “red stone.”
- The Latin element is connected with rubeus and ruber, meaning “red.”
- These forms are ultimately associated with the Proto-Indo-European root reudh-, meaning “red” or “ruddy.”
Short History of Ruby
- Old English (450–1100): The modern English word ruby was not yet established in Old English. English speakers used native words related to red colors, while the later gemstone term developed through French and Latin.
- Middle English (1100–1500): Forms such as rubi and rubie appeared in English around the late 12th and early 13th centuries. The word referred to the valuable red gemstone.
- Modern English (1500–Present): Ruby developed additional uses. By around 1500 it could describe something having the color of a ruby, and from the 1570s it was also used as a name for a particular red color.
