Unexpected meanings
In its Latin origin, this compliment was an insult
Published on October 11, 2026
Words of Latin origin abound in the English language, many of them with an original meaning quite similar to the current one. But some words, however, might surprise us when we look up their etymology. What does being genuine have to do with your knees? Which word comes from people gossiping in a street corner? Which compliment started as an insult? Here are 10 unexpected Latin etymologies.
Genuine
Some linguists state that "genuine" comes from gignere, "to produce", related to the idea of giving birth. In this sense, something genuine would be something innate, not acquired. But there is an alternative origin proposed that links the term to genu, "knee". In Ancient Rome, newborns would be placed in front of their father to be acknowledged. If the father decided to recognize the infant as their true child, he would pick them up and place them on his knee.
Mortgage
Borrowed from French, the term "mortgage" is not completely of Latin origin. Its second half, gage, comes from a Germanic term for "pledge". Mort, however, comes from mortuus, meaning "dead". What do "dead pledges" have to do with real estate loans? In its original sense, mortgages were pledges that resulted in "death": either the pledge died when it was fulfilled, or when one of the parties failed to pay, which "killed" their rights over the collateral.
Porcupine
At first glance, we might not see the Latin roots of this word, but they become quite clear when we separate the two parts that compose it: Porcus, "pig", and spina, "thorn", which makes a porcupine a "thorny pig". English adopted this name through the French porc-espin, which resulted in the Middle English porke despyne. The name had several variations in English (including the Shakespearean porpentine) before settling into its current form.
Muscle
What do muscles and rodents have in common? More than you might think. The Latin term for "muscle" comes from the diminutive form of mus, "mouse". For Ancient Romans, the movement of the muscle tissue under the skin looked like a small mouse scurrying around, which made the name musculus, "little mouse," quite fitting.
Trivia
Trivia lovers might be delighted to learn that, since the time of the Ancient Romans, fun facts were shared just for the sake of sharing them. From the word trivium, "where three roads meet", trivia was used to describe road intersections where people gathered to chat, gossip, and share "trivial" news. Trivia might be of little consequence since its origins, but it has been loved and shared for centuries.
Nice
Being called "nice" might not be the highest of compliments, but it is also not a bad thing to be called. That is, in the last few centuries. In its Latin origin, nescius (from nescire, "to not know", "to ignore") was undoubtedly insulting, and it continued to be up until the 15th century, when "nice" lost its meaning of "fool", "ignorant", or "fussy", and adopted the meaning of "precise" and later on "agreeable" and "kind".
Placenta
The placenta is an extraordinary and fascinating organ, but its name is almost underwhelming in its simplicity. It was named in the 16th century by Italian anatomist Realdo Colombo, who chose the name placenta uterina, Latin for "uterine cake". Yes, placenta is the Latin word for "cake" or "flatbread". Why did Colombo choose the name? To him, the shape of the placenta resembled a traditional baked flat cake.
Uncle
In English, many familiar relations kept their original Old English form, but some were replaced by their Norman-French equivalent. "Uncle" (in Old English, ēam for maternal uncles and fædera for paternal uncles) was adopted from the French oncle, derived from the Latin avunculus. While avunculus was used in Latin for maternal uncles and is often translated as "mother’s brother", it is actually the diminutive of avus, "grandfather", which made your maternal uncle your "little grandfather".
Candidate
We are used to suspecting the hidden motivations of political candidates, a reality that makes the etymology of "candidate" sound ironic. The term comes from the Latin candidus, meaning "shining white". Political candidates in ancient Rome would wear a bright white robe or toga candida as a sign of their purity, honesty, and good reputation, and they were known as candidatus or "clothed in white".
Desire
If you were to look for the Latin root of the word "desire", you would find the verb desiderare, meaning "to long for", "to wish", or "to demand". But what is behind desiderare? While some experts consider this a folk etymology**, others link** desiderare to de sidere ("from the stars"), from sidus ("heavenly body" or "star"), connecting "desire" with something ruled by or wished upon the stars.
