What Does the Name Rubylou Mean?
Rubylou is an English compound given name combining Ruby and Lou. Ruby is the name of the red gemstone; the word comes through Old French rubi from Medieval Latin rubinus, from Latin rubeus, "red." Lou is commonly a short form of Louise or Louis, names from the Germanic Hludwig (Latinized Ludovicus), composed of hlud, "famous," and wig, "warrior" or "battle"; its customary meaning is "famous warrior." Because Rubylou is a compound, its meaning is usually understood as the combined sense of these elements rather than as a single inherited name with its own etymology.
Rubylou Name History & Origins
Rubylou is formed by joining two established English given names, Ruby and Lou. The run-together spelling belongs to the English habit of writing double names as one word, alongside forms such as Ruby Lou or Ruby-Lou. Its history is therefore the history of its two elements and of that naming pattern.
Ruby comes from the gemstone word, borrowed into English from Old French rubi, which goes back to Medieval Latin rubinus and Latin ruber. Ruby became a familiar female given name in the 19th century, when gemstone names were in fashion.
Lou is an English short form of Louis and Louise. These descend from the Germanic name Hludwig, Latinized as Ludovicus and represented in French as Louis; Louise is the feminine form. In a woman's compound name such as Rubylou, Lou is most often understood as the short form of Louise.
