COSM

Root Meaning:

COSM comes from the Greek word for “order.” Since the Greeks believed the universe was an orderly place, words in this group usually relate to the universe. So cosmonaut was the word for a space traveler from the former Soviet Union. (The roots of our own word, astronaut, suggest “star traveler” instead.) Oddly enough, cosmetics comes from the same root, since putting things in order is similar to decorating something—such as your face.

Etymology:

Latin
4 words derived from this root

Words from this root:

cosmos

/ˈkɒzmɒs/
Definition:
(1) The universe, especially when it is viewed as orderly and systematic. (2) Any orderly system that is complete in itself.
Example:
The astronomer, the biologist, and the philosopher all try in their own ways to make sense of the cosmos.
Explanation:
*Cosmos* often simply means “universe.” But the word is generally used to suggest an orderly or harmonious universe, as it was originally used by Pythagoras in the 6th century B.C. Thus, a religious mystic may help put us in touch with the cosmos, and so may a physicist. The same is often true of the adjective *cosmic*: Cosmic rays (really particles rather than rays) bombard us from outer space, but cosmic questions come from human attempts to find order in the universe.

cosmology

/kɒzˈmɒlədʒi/
Definition:
(1) A theory that describes the nature of the universe. (2) A branch of astronomy that deals with the origin and structure of the universe.
Example:
New Age teachers propose a cosmology quite unlike the traditional Jewish, Christian, or Islamic ways of viewing the universe.
Explanation:
Most religions and cultures include some kind of cosmology to explain the nature of the universe. In modern astronomy, the leading cosmology is still the Big Bang theory, which claims that the universe began with a huge explosion that sent matter and energy spreading out in all directions. One reason why fans watch *Star Trek* is for the various cosmologies depicted in the show, including different conceptions of space, time, and the meaning of life.

microcosm

/ˈmaɪkrəkɒzəm/
Definition:
Something (such as a place or an event) that is seen as a small version of something much larger.
Example:
The large hippie communes of the 1960s and '70s were microcosms of socialist systems, with most of socialism's advantages and disadvantages.
Explanation:
A troubled urban school can look like a microcosm of America's educational system. A company's problems may be so typical that they can represent an entire small country's economic woes “in microcosm.” *Microcosm,* and especially its synonym *microcosmos,* are also sometimes used when talking about the microscopic world. The documentary film *Microcosmos* is devoted to the remarkable insect life in an ordinary meadow on a single summer's day.

cosmopolitan

/ˌkɒzməˈpɒlɪtən/
Definition:
(1) Having international sophistication and experience. (2) Made up of persons, elements, or influences from many different parts of the world.
Example:
New York, like most cosmopolitan cities, offers a wonderful array of restaurants featuring foods from around the world.
Explanation:
Since *cosmopolitan* includes the root *polit-,* from the Greek word for “citizen”, someone who is cosmopolitan is a “citizen of the world.” She may be able to read the morning paper in Rio de Janeiro, attend a lecture in Madrid, and assist at a refugee camp in Uganda with equal ease—and maybe all in the same week. And a city or a country that is cosmopolitan has aspects and elements that come from various countries.

SCI

Root Meaning:

SCI comes from the Latin verb scire, “to know” or “to understand.” The root appears in such common words as science, which originally meant simply “knowledge,” and conscience, meaning “moral knowledge.” And to be conscious is to be in a state where you are able to know or understand.

Etymology:

Latin
4 words derived from this root

Words from this root:

conscientious

/ˌkɒnʃiˈɛnʃəs/
Definition:
(1) Governed by morality; scrupulous. (2) Resulting from painstaking or exact attention.
Example:
New employees should be especially conscientious about turning in all their assignments on time.
Explanation:
*Conscience* and its adjective *conscientious* both come from a Latin verb meaning “to be aware of guilt.” *Conscientious* indicates extreme care, either in observing moral laws or in performing assigned duties. A conscientious person is someone with a strong moral sense, who has feelings of guilt when he or she violates it. A conscientious worker has a sense of duty that forces him or her to do a careful job. A conscientious report shows painstaking work on the part of the writer. And a *conscientious objector* is someone who, for reasons of conscience, refuses to fight in an army.

nescience

/ˈnɛʃəns/
Definition:
Lack of knowledge or awareness: ignorance.
Example:
About once every class period, my political-science professor would angrily denounce the nescience of the American public.
Explanation:
This word, which means literally “non-knowledge,” is only used by intellectuals, and the same is true of its adjective, *nescient*. We all have heard the remarkable facts: 40% of us believe that humans and dinosaurs lived on earth at the same time; 49% believe that the President can ignore the Constitution; 60% can't name the three branches of government; 75% can't find Israel on a map; and so on. Is it any wonder we Americans are sometimes called nescient?

prescient

/ˈpriːʃənt/
Definition:
Having or showing advance knowledge of what is going to happen.
Example:
For years she had read the *Wall Street Journal* every morning, looking for prescient warnings about crashes, crises, and catastrophes on the horizon.
Explanation:
Being truly prescient would require supernatural powers. But well-informed people may have such good judgment as to appear prescient, and *prescient* is often used to mean “having good foresight.” Some newspaper columnists may seem prescient in their predictions, but we can't help suspecting that any apparent *prescience* is usually the result of leaks from people with inside knowledge.

unconscionable

/ʌnˈkɒnʃənəbəl/
Definition:
(1) Not guided by any moral sense; unscrupulous. (2) Shockingly excessive, unreasonable, or unfair.
Example:
When the facts about how the cigarette industry had lied about its practices for decades finally came out, most Americans found the behavior unconscionable.
Explanation:
Something that can't be done in good *conscience* is unconscionable, and such acts can range from betraying a confidence to mass murder. For a five- syllable word, *unconscionable* is actually quite common. This is partly because it isn't always used very seriously; so, for example, a critic is free to call a fat new book “an unconscionable waste of trees.” In law, an unconscionable contract is one that, even though it was signed by both parties, is so ridiculous that a judge will just throw it out.

Follow along with Alex and Ben

Alex
Hello everyone, and welcome back to Word Builders, the show where we construct a bigger vocabulary, one root at a time.
Ben
Hello Alex! So, I was staring at the stars last night and had a big question. How do we even begin to talk about something as huge as the universe?
Alex
That is the perfect question for today, Ben. We're tackling the universe and our knowledge of it with two powerful roots. The first comes from Greek, and the second from Latin.
Ben
Sounds like a cosmic journey!
Alex
Exactly! Our first root is C-O-S-M, from the Greek word for “order.” The ancient Greeks saw the universe as an orderly system, so this root often relates to the universe itself.
Ben
So, like the word cosmos?
Alex
Precisely. Our first word is cosmos. It’s pronounced koz-moss. It means the universe, especially when you think of it as an orderly and harmonious system.
Ben
So it’s more than just "space"? It implies there’s a structure to it all.
Alex
That's the key. A philosopher might try to make sense of the cosmos, just as an astronomer does. It suggests a grand, understandable design.
Ben
Okay, so if cosmos is the thing itself, what about the study of it? I think I've heard a similar word.
Alex
You're one step ahead. That brings us to cosmology. That’s pronounced koz-mol-uh-jee. The "-logy" part means "study of," so cosmology is a theory about the nature, origin, and structure of the universe.
Ben
Like the Big Bang theory?
Alex
That’s the most famous cosmology in modern astronomy! But many cultures and religions have their own cosmologies to explain where everything came from and how it all works.
Ben
That makes sense. We’ve gone from the giant cosmos to the theories about it. What if we want to talk about something small that reflects that big order?
Alex
A fantastic transition. That brings us to microcosm. We say it my-kroh-koz-um. The prefix "micro" means small, so a microcosm is literally a "small world" or a small version of something much larger.
Ben
Can you give me an example?
Alex
Of course. You could say a well-run community garden is a microcosm of a successful, cooperative society. It’s a small-scale model that shows how the larger system works.
Ben
I see. So from the small world to the whole world… what about a person who seems to belong everywhere?
Alex
You're thinking of someone who is cosmopolitan. Pronounced koz-mo-pol-i-tan. This word combines "cosm," for world, with a root from the Greek word for "citizen." A cosmopolitan person is a "citizen of the world."
Ben
Someone who is sophisticated and has international experience.
Alex
Exactly. They’re comfortable in different cultures. We also use it to describe cities. A cosmopolitan city, like New York or London, is filled with influences and people from all over the globe.
Ben
From the cosmos to a cosmopolitan city. That was a great set. What’s our next root?
Alex
From the order of the universe, we now turn to how we know things. Our second root is S-C-I, from the Latin verb ‘scire’, which means “to know” or “to understand.”
Ben
Oh, like in the word science!
Alex
Perfect! Science literally just meant “knowledge.” Another one is conscience, which is our moral knowledge. This brings us to our first word from this root: conscientious.
Ben
That’s a long one. How do we say it?
Alex
It’s kon-shee-en-shuss. It means being guided by your conscience or morality. It also means being painstaking and careful. A conscientious student double-checks their work, driven by a sense of duty.
Ben
So it’s about knowing what’s right, and then doing it carefully.
Alex
You've got it. A conscientious person has a strong moral compass.
Ben
Okay, so if SCI means "to know," is there a word for *not* knowing?
Alex
There is, though it’s a bit more formal. The word is nescience. Pronounced nesh-unce. The "ne" prefix means "not," so it literally means "not-knowing," or simply, ignorance.
Ben
So you might say the public has a nescience about certain political issues?
Alex
An expert might phrase it that way, yes. It’s a powerful word to describe a lack of knowledge or awareness on a topic.
Ben
So we have knowing, and not knowing. What about knowing something *before* it happens?
Alex
Another brilliant question, Ben. That would be the word prescient. Pronounced pree-shent. The prefix "pre" means "before," so to be prescient is to know something before it happens.
Ben
So, like a psychic?
Alex
It can imply that, but more often we use it to describe someone with incredible foresight. An investor who sells all their stocks right before a market crash might be described as prescient. It suggests sharp, forward-thinking judgment.
Ben
I like that. It’s a smart word. For our last one, I want to ask about a word that sounds related, but much more serious: unconscionable.
Alex
Ah, an important one. Unconscionable. We say it un-kon-shun-uh-bull. If your conscience is your moral knowledge, then an unconscionable act is one that is not guided by any moral sense at all.
Ben
So it means something is unscrupulous or deeply immoral?
Alex
Yes, and it also has a second meaning: shockingly excessive or unfair. For example, lying to the public about a dangerous product is unconscionable. In legal terms, an unconscionable contract is so one-sided a judge would throw it out.
Ben
Wow. That word carries a lot of weight.
Alex
It certainly does. It’s for actions that go completely against our shared sense of right and wrong.
Ben
What a journey. From the whole universe to the core of our conscience. Can we do a quick review, Alex?
Alex
Let’s do it. First we had cosmos, the orderly universe. Then cosmology, a theory about that universe.
Ben
A microcosm is a small version of something large, and a cosmopolitan person is a citizen of the world.
Alex
Then we had conscientious, meaning guided by morals and very careful. And nescience, which is a lack of knowledge.
Ben
Prescient is knowing something in advance, and finally, unconscionable means shockingly immoral or unfair.
Alex
An excellent summary. You’re building your vocabulary with real skill.
Ben
I’m trying! Thanks so much, Alex. This was fascinating.
Alex
My pleasure. And thank you to everyone out there for listening to Word Builders.
Ben
