POLY

Root Meaning:

POLY comes from polys, the Greek word for “many.”

Etymology:

Latin
4 words derived from this root

Words from this root:

polyp

/ˈpɒlɪp/
Definition:
(1) A sea invertebrate that has a mouth opening at one end surrounded by stinging tentacles. (2) A growth projecting from a mucous membrane, as on the colon or vocal cords.
Example:
She had had a polyp removed from her throat, and for two weeks afterward she could only whisper.
Explanation:
This term comes from *polypous*, a Greek word for “octopus,” which meant literally “many-footed.” To the untrained eye, the invertebrate known as the polyp may likewise appear to be many-footed, though it never walks anywhere since its “feet” are tentacles, used for stinging tiny organisms which the polyp then devours. The types of tumor known as polyps got their name because some seem to be attached to the surface by branching “foot”- like roots, even though most do not. Polyps of the nose or vocal cords are usually only inconvenient, causing breathing difficulty or hoarseness, and can be removed easily; however, polyps in the intestines can sometimes turn cancerous.

polyglot

/ˈpɒlɪɡlɒt/
Definition:
(1) One who can speak or write several languages. (2) Having or using several languages.
Example:
As trade between countries increases, there is more need for polyglots who can act as negotiators.
Explanation:
*Polyglot* contains the root *glot,* meaning “language.” It is used both as a noun and as an adjective. Thus, we could say that an international airport is bound to be *polyglot*, with people from all over the world speaking their native languages. One of history's more interesting polyglots was the Holy Roman Emperor Charles V, who claimed that he addressed his horse only in German, conversed with women in Italian and with men in French, but reserved Spanish (his original language) for his talks with God.

polymer

/ˈpɒlɪmə(r)/
Example:
Nylon, a polymer commercially introduced in 1938, can be spun and woven into fabrics or cast as tough, elastic blocks.
Explanation:
There are many natural polymers, including shellac, cellulose, and rubber. But synthetic polymers only came into being around 1870 with Celluloid, known especially for its use in photographic film. After many decades of development, the *polymeric* compounds now include *polypropylene,* used in milk crates, luggage, and hinges; *polyurethane,* used in paints, adhesives, molded items, rubbers, and foams; and *polyvinyl chloride* (PVC), used to make pipes that won't rust. And let's not forget *polyester*, which gave us a lot of uncool clothing in the 1970s but whose strength and resistance to corrosion have ensured that it remains an extremely useful material for all kinds of goods.

polygraph

/ˈpɒlɪɡrɑːf/
Example:
My brother-in-law is completely law-abiding, but he's such a nervous type that he's failed two polygraph tests at job interviews.
Explanation:
With its *graph-* root (see GRAPH), *polygraph* indicates that it writes out several different results. A polygraph's output consists of a set of squiggly lines on a computer screen, each indicating one function being tested. The functions most commonly measured are blood pressure, breathing rate, pulse, and perspiration, all of which tend to increase when you lie. Polygraphs have been in use since 1924, and have gotten more sensitive over the years, though many experts still believe that they're unreliable and that a prepared liar can fool the machine. They're used not only for law enforcement but perhaps more often by employers—often the police department itself!—who don't want to hire someone who has broken the law in the past but won't admit to it.

PRIM

Root Meaning:

PRIM comes from primus, the Latin word for “first.”

Etymology:

Latin
4 words derived from this root

Words from this root:

primal

/ˈpraɪml/
Definition:
Basic or primitive.
Example:
There was always a primal pleasure in listening to the rain beat on the roof at night and dropping off to sleep in front of the fire.
Explanation:
*Primal* generally describes something powerful and almost instinctual. So when we speak of the primal innocence of youth or the primal intensity of someone's devotion, we're suggesting that the emotions or conditions being described are basic to our animal nature. Sitting around a campfire may feel like a primal experience, in which we share the emotions of our cave- dwelling ancestors. Intense fear of snakes or spiders may have primal roots, owing to the poison that some species carry. In “primal scream” therapy, popular in the 1970s, patients relive painful childhood experiences and express their frustration and anger through uncontrolled screaming and even violence.

primer

/ˈpraɪmə(r)/
Definition:
(1) A small book for teaching children to read. (2) A small introductory book on a subject.
Example:
She announced that she'd be passing out a primer on mutual funds at the end of the talk.
Explanation:
Primers were once a standard part of every child's education. The first primer printed in North America, *The New England Primer* (ca. 1690), was typical; it contained many quotations from the Bible and many moral lessons, and the text was accompanied by numerous woodcut illustrations. We no longer use the word in early education, but it's widely used in everyday speech. Notice how *primer* is pronounced; don't mix it up with the kind of paint that's pronounced with a long *i* sound.

primate

/ˈpraɪmeɪt/
Definition:
Any member of the group of animals that includes human beings, apes, and monkeys.
Example:
Dr. Leakey sent three young women to work with individual primates: Jane Goodall with the chimpanzees, Dian Fossey with the gorillas, and Birute Galdakis with the orangutans.
Explanation:
It was the great biologist Carolus Linnaeus who gave the primates their name, to indicate that animals of this order were the most advanced of all. Linnaeus listed human beings with the apes a hundred years before Charles Darwin would publish his famous work on evolution. When people told him that our close relationship to the apes and monkeys was impossible because it disagreed with the Bible, he responded that, from the biological evidence, he simply couldn't come to a different conclusion. Among the mammals, the primates are distinguished by their large brains, weak sense of smell, lack of claws, long pregnancies, and long childhoods, among other things. Along with the apes and monkey, the Primate order includes such interesting animals as the lemurs, tarsiers, galagos, and lorises.

primordial

/praɪˈmɔːdiəl/
Definition:
(1) First created or developed. (2) Existing in or from the very beginning.
Example:
Many astronomers think the universe is continuing to evolve from a primordial cloud of gas.
Explanation:
*Primordial* can be traced back to the Latin word *primordium,* or “origin,” and applies to something that is only the starting point in a course of development or progression. A primordial landscape is one that bears no sign of human use, and a primordial cell is the first formed and least specialized in a line of cells. The substance out of which the earth was formed and from which all life evolved is commonly called “the primordial ooze” or “the primordial soup”—even by scientists.

Conversation Script

Follow along with Alex and Ben

!Speaker1: Hello and welcome back to Word Builders. I’m Alex. Speaker2: And I’m Ben. Alex, have you ever wished you could speak multiple languages, or do you prefer to be the first to try something new? Speaker1: That's a tough one! But it’s the perfect question for today’s show. Speaker2: Oh? How so? Speaker1: Because today, we're exploring two fantastic roots that cover both of those ideas! We’re diving into "POLY," the Greek root for "many," and "PRIM," the Latin root for "first." Speaker2: From many to one, or at least, to first. I like it! Let's start with 'many'. Speaker1: Excellent. Our first root is POLY, from the Greek word *polys*, meaning “many.” And our first word is polyp. Speaker2: Polyp. I think I’ve heard this in two very different contexts. One is a sea creature, and the other is a medical thing, right? Speaker1: Exactly. A polyp can be a sea invertebrate with stinging tentacles, or it can be a growth projecting from a mucous membrane, like in your colon or on your vocal cords. Speaker2: How did one word end up with two such different meanings? Speaker1: It comes from the Greek word *polypous*, which literally meant “many-footed,” and was their word for an octopus. The sea creature polyp seemed to have many feet, even though they're tentacles. Speaker2: Ah, and the medical growth? Speaker1: That got its name because some of them look like they're attached by little branching "foot"-like roots. Speaker2: Many-footed. That makes sense. So, on to our next word, what about polyglot? Speaker1: A polyglot is someone who can speak or write several languages. The word can also be an adjective describing a place that has or uses many languages, like an international airport. Speaker2: I see the 'poly' for 'many'. What does the 'glot' part mean? Speaker1: 'Glot' comes from a root meaning “language.” So, many languages. There's a great story about a famous polyglot, the Holy Roman Emperor Charles the Fifth. Speaker2: Do tell! Speaker1: He claimed he spoke German to his horse, Italian to women, French to men, and his native Spanish only when he was talking with God. Speaker2: Wow. A language for every occasion! What’s our next “many” word? Speaker1: Our next one is polymer. Speaker2: That sounds like chemistry class. Plastics and things? Speaker1: You've got it. A polymer is a chemical compound where molecules combine to form larger molecules with repeating structural units. Think of a long chain made of many identical links. Speaker2: So like nylon or PVC pipes? Speaker1: Precisely. Nylon was a huge commercial polymer. There are also natural ones like rubber. The name literally means "many parts." This also gives us polyester, which gave us some memorable fashion in the seventies. Speaker2: I've seen the photos. Let's move on to our last POLY word. Speaker1: That would be polygraph. Speaker2: The lie detector! So 'poly' for many, but what is 'graph'? Speaker1: ‘Graph’ is from a root meaning “to write.” A polygraph literally writes out many results at once. It records changes in functions like blood pressure, pulse, and breathing. Speaker2: And the idea is that those things change when you lie. Speaker1: That's the theory. They’ve been used since the nineteen twenties, but many experts still question their reliability. Speaker2: Okay, so from POLY for “many,” where are we headed next? Speaker1: We're jumping from Greek to Latin. Our next root is PRIM, from the Latin word *primus*, meaning “first.” Speaker2: First! What's our first word for "first"? Speaker1: Appropriately enough, it’s primal. It means basic or primitive. Speaker2: So, primal instincts? That kind of thing? Speaker1: Exactly. It describes something powerful and instinctual, connected to our earliest, most basic animal nature. The comfort of sitting around a campfire might feel like a primal experience. Speaker2: I can see that. What’s next on the 'first' list? Speaker1: Next up is primer. Spelled P-R-I-M-E-R. Speaker2: A primer. Isn’t that a type of paint you put on first? Speaker1: It can be, but that's pronounced with a long 'i' sound. The word we're talking about is pronounced primer, with a short 'i'. It means a small introductory book on a subject. Speaker2: Oh! So you could read a primer on mutual funds, for example. Speaker1: You could indeed. Historically, it was also a small 'first' book for teaching children to read. Speaker2: Good to know. Different pronunciations for different meanings. What’s our third word? Speaker1: Primate. Speaker2: Like monkeys, apes, and us humans. Why are we called primates? Speaker1: The biologist Carolus Linnaeus named the group. He chose primate to mean the 'first' or most advanced order of animals. He actually listed human beings with apes a hundred years before Darwin published his famous work on evolution. Speaker2: So we're considered the 'first' among animals because of things like our large brains and long childhoods. Speaker1: That’s right. The order also includes fascinating animals like lemurs and tarsiers. Speaker2: Very cool. And our final word for today? Speaker1: Our last one is primordial. Speaker2: How is that different from primal? They sound very similar. Speaker1: Great question. While 'primal' refers to basic instincts, 'primordial' refers to something that was first created or has existed from the very beginning of time. Speaker2: So like a primordial landscape that's completely untouched? Speaker1: Exactly. Or the famous "primordial ooze"—that substance from which all life on Earth supposedly evolved. It means the absolute origin, the very first starting point. Speaker2: That was a fantastic journey, from many things to the very first things. Can we do a quick review? Speaker1: Of course. From the Greek root POLY, meaning “many,” we had polyp, a many-footed creature or growth. Speaker2: Polyglot, someone who speaks many languages. Speaker1: Polymer, a substance with a structure of many repeating units. Speaker2: And polygraph, a machine that writes down many bodily signals. Speaker1: Then from the Latin root PRIM, for “first,” we had primal, meaning basic or instinctual. Speaker2: Primer, an introductory or first book. Speaker1: Primate, the first or highest order of animals. Speaker2: And primordial, existing from the very first moments of creation. Speaker1: And that is all the time we have for today. You did wonderfully, Ben. Speaker2: I learned a lot! Thanks, Alex. And thanks to all of you out there for listening. Speaker1: Join us next time on Word Builders, where we’ll continue to construct a better vocabulary, one root at a time. Speaker2: Until then, goodbye
