About places or things in the very far north or south of the world, near the North Pole or South Pole.
Vzorec užití:

Častá chyba:
Learners sometimes use "polar" to mean any cold place. Strictly, this sense is about the areas around the North and South Poles, not just cold regions in general.
Synonyma
Arctic (Usually refers specifically to the North Polar region, while "polar" can refer to either pole.)
|
Antarctic (Usually refers specifically to the South Polar region, while "polar" can refer to either pole.)
Antonyma
equatorial (Refers to areas around the Earth's equator, the opposite of the far northern or southern polar areas.)

2
extremely cold like the poles
Very, very cold, like the North or South Pole.
Vzorec užití:
polar [air/wind/weather/night]
Častá chyba:
Learners may confuse "polar" with "polarizing" (which means causing strong disagreement). "Polar" in this sense only describes very cold conditions.
Synonyma
freezing (More common in everyday speech; "polar" often sounds stronger or more dramatic.)
|
frigid (Very similar strength; "frigid" is slightly more formal or literary.)
Antonyma
balmy (Describes pleasantly warm weather, the opposite of extremely cold conditions.)

3
completely opposite or extreme
Describes things that are totally different from each other.
Vzorec užití:
polar [views/opinions/positions]
Častá chyba:
Learners may think "polar" here always needs the word "opposites". It is most common in the phrase "polar opposites", but it can also modify other nouns like "views" or "positions" to mean extremely different.
Synonyma
opposite (General word for being different in direction or quality; "polar" emphasizes complete or extreme difference.)
|
diametrically opposed (Formal phrase that, like "polar", stresses total opposition.)
Antonyma
similar (Indicates things are alike, the contrast of being at opposite extremes.)

4
having separated electric charges
Describes a molecule or chemical bond where electric charge is not shared equally, so one end is more positive and the other more negative.
Vzorec užití:
polar [molecule/bond/solvent/group]
Častá chyba:
Learners may mix up "polar" and "ionic". While many ionic compounds interact strongly with polar substances, "ionic" refers to charged ions, and "polar" refers to uneven charge inside a molecule or bond.
Synonyma
charged (General word for having electrical charge; "polar" specifically refers to unequal charge distribution within a molecule or bond.)
Antonyma
nonpolar (Describes molecules or bonds without significant separation of charge, the technical opposite of polar in chemistry.)

5
relating to a mathematical or physical pole
Used in math and science to talk about lines, orbits, or points that are based on a central axis or pole.
Vzorec užití:
polar [coordinates/orbit/axis/angle]
Častá chyba:
Learners may assume "polar coordinates" are only about cold places. In mathematics, this term is about a way of locating points using a distance and an angle from a center point, not about climate.
Synonyma
axial (General term for something related to an axis; "polar" is used in specific mathematical and astronomical systems.)
Antonyma
equatorial (In astronomy, refers to regions or orbits around the equator, contrasting with polar regions or orbits around a pole.)

6
the region around a pole
The very far north or south part of the Earth, near the North Pole or South Pole.
Vzorec užití:
the polar / the polars
Častá chyba:
This noun use of "polar" is less common in everyday English; learners may expect it only as an adjective. In general English, it is safer to say "the polar regions" instead of just "the polar".
Synonyma
polar region (More explicit phrase for the same concept; "polar" as a noun is more technical or shorthand in scientific writing.)
Antonyma
tropics (Refers to the warm regions around the equator, contrasted with the cold polar regions.)
