소수
sosu[ˈsʰo̞(ː)sʰu]
The English phrase 'decimals' is translated into Korean as 소수 (sosu).
소수 refers to numbers that use a decimal point to show a fractional part of a whole.
Which one should you use?
The word 소수 is a homonym in a mathematical context. It can mean both 'decimal' and 'prime number' depending on the specific topic being discussed. To specifically refer to the 'decimal point' itself, use the term 소수점.
How do you pronounce it?
sosu
What mistakes should you avoid?
Because the Korean word for 'decimal' is identical in spelling and pronunciation to the word for 'prime number' (also 소수), be careful to ensure the mathematical context is clear to avoid confusion.
Did you know?
- The term 소수 can also be understood as 'minority' in certain linguistic contexts, as it shares the same Hanja roots as 'small number'.
- If you are studying number theory, you must specify your context, as the term 소수 for 'prime number' is derived from different Hanja than the word for 'decimal'.
- Because of the linguistic overlap, Korean students often use extra-linguistic cues, like pointing to a specific part of a number, to ensure they are discussing 'decimals' and not 'prime numbers'.
