Korean Consonants: Plain ㅅ vs Tense ㅆ and Saying 정말 (Really)
Learn to hear and say plain ㅅ and tense ㅆ in Korean, and pronounce 정말 'really' naturally with correct tense consonants and clear vowels.
By TheaFirst conversations · Yapr Learn
Korean distinguishes plain consonants like ㅅ (s) from tense consonants like ㅆ (ss). The tense version is produced with a tighter, more forced vocal tract and no puff of air. This lesson teaches you to hear and produce that contrast, then applies it to the common word 정말 (really). You will practice minimal pairs, a polite question pattern, and a short dialogue so you can ask and answer naturally without confusing 사 and 싸.
By the end, you can…
- tell the difference between plain ㅅ and tense ㅆ in listening and speaking.
- pronounce 정말 (really) with correct tense ㅆ and clear vowels.
Listen once. Try it slowly. Then say it without looking.

Make it make sense
Useful pattern
The plain vs tense contrast appears in many everyday words. Plain ㅅ is like a light English 's' with a relaxed tongue. Tense ㅆ is made with more muscle tension and no puff of air. Compare 사다 (sa-da, to buy) and 싸다 (ssa-da, to be cheap). Also 비싸요 (bi-ssa-yo, it is expensive) uses tense ㅆ. When you say 정말 (jeong-mal, really), the first syllable begins with plain ㅈ, not ㅆ, so do not tense it. The tense consonant in this lesson is mainly in 싸요 and 비싸요. Practice switching: 사요 (sa-yo) vs 싸요 (ssa-yo).
When to use it
Use 정말 to mean 'really' or 'truly' in polite conversation. It can stand alone as a question: 정말? (jeong-mal?, Really?) or with a polite ending: 정말이에요? (jeong-mal-i-e-yo?, Is that really true?). When you want to say something is really cheap, combine them: 정말 싸요. (jeong-mal ssa-yo, It is really cheap.) If you are asking staff about a price, start with 이거 얼마예요? (i-geo eol-ma-ye-yo?, How much is this?) and listen for 싸요 or 비싸요. Do not use tense ㅆ in 정말; that would change the word.
Listen to each line, then take one part and reply out loud.
이거 얼마예요?
How much is this?i-geo eol-ma-ye-yo오천 원이에요.
It is 5,000 won.o-cheon won-i-e-yo정말 싸요!
Really cheap!jeong-mal ssa-yo네, 정말 싸요.
Yes, it is really cheap.ne, jeong-mal ssa-yoA little context goes a long way
In Korean, tense consonants like ㅆ can feel emphatic. Using 정말 adds sincerity or surprise. With staff, the polite -요 style is safe and friendly. Avoid slang or casual speech unless you know the person well.
One thing to watch for
Pronouncing 정말 with a tense ㅉ, as if it were 쩡말.
Try this instead: 정말 begins with plain ㅈ, not tense ㅉ. Say jeong-mal with a relaxed ㅈ. The tense ㅆ appears in words like 싸요 (ssa-yo).
Your turn
Try answering out loud before checking a possible answer.
1Which word means 'cheap' and uses tense ㅆ?
Show a sample answer
싸요 (ssa-yo)
싸요 uses tense ㅆ. 사요 (sa-yo) means 'I buy' with plain ㅅ. Both are valid words; the tense distinction changes meaning.
2How do you say 'Really?' politely in Korean?
Show a sample answer
정말이에요? (jeong-mal-i-e-yo?)
This is a polite question. 정말? is also correct in casual speech, but the -이에요? ending is safer with strangers.
3What is the difference between ㅅ and ㅆ?
Show a sample answer
ㅅ is plain and lightly aspirated; ㅆ is tense, tighter, and not aspirated.
The tense ㅆ requires more muscle tension. Both are valid sounds; they contrast in words like 사요 and 싸요.
Keep ㅅ relaxed and ㅆ tight. Say 정말 with plain ㅈ, and use 싸요 for 'cheap'. Practice the pair until the tense contrast feels natural.
