살다 ("to live") is the model for ㄹ-stem verbs — a large, common family (알다 "know," 만들다 "make," 놀다 "play," 열다 "open," 팔다 "sell," 멀다 "be far"). It looks intimidating because its final ㄹ vanishes in certain forms, and textbooks often file it under "irregular." Don't be fooled: the ㄹ-drop is completely regular. It fires in one fixed environment, on every ㄹ-stem, without exception. Learn the trigger set once and the entire class is yours. The two things that separate 살다 from an ordinary consonant stem like 먹다: the ㄹ drops before certain sounds, and a ㄹ-stem never takes the 으 buffer.
The stem at a glance
- Dictionary form: 살다 · stem: 살- · ends in: batchim ㄹ · harmony vowel: ㅏ → 아 (살아요)
- The drop rule: the stem ㄹ disappears before an ending beginning with ㄴ, ㅂ, ㅅ, or the honorific 시/세. Elsewhere it stays.
- No 으, ever: unlike 먹다, a ㄹ-stem does not insert the buffer 으. It drops the ㄹ (사세요, not ×살으세요) or keeps it (살면, not ×살으면) — but 으 never appears.
The one rule: when the ㄹ drops and when it stays
A classic mnemonic for the trigger consonants is the nonsense syllable set ㄴ · ㅂ · ㅅ (plus 시/세). If the ending starts with one of those, the ㄹ is gone; if it starts with anything else — a vowel, ㄱ, ㅁ, ㄷ, ㅈ — the ㄹ holds.
| ㄹ DROPS before… | Example | ㄹ STAYS before… | Example |
|---|---|---|---|
| ㄴ (-는, -ㄴ다, -니까) | 사는, 산다, 사니까 | vowel 아/어 | 살아요, 살았어요 |
| ㅂ (-ㅂ니다, -ㅂ시다) | 삽니다, 삽시다 | ㄱ (-고, -겠-, -기) | 살고, 살겠어요, 살기 |
| ㅅ (-세요, -십시오) | 사세요, 사십시오 | ㅁ (-(으)면) | 살면 |
| ㄷ (-던), ㅈ (-지, -자) | 살던, 살지, 살자 |
Two forms deserve a footnote. The prospective attributive -(으)ㄹ has the stem ㄹ absorb the ending's ㄹ, leaving a single 살 ("(place) one will live"). And the past attributive is 산 (살 + ㄴ, ㄹ drops), which is spelled identically to the present-tense plain form 산다's root — context tells them apart.

Full paradigm: finite forms by speech level
| Mood / tense | 합니다체 (formal) | 해요체 (informal-polite) | 반말 (intimate) | 한다체 (plain/written) |
|---|---|---|---|---|
| Present | 삽니다 samnida | 살아요 sarayo | 살아 sara | 산다 sanda |
| Past | 살았습니다 saratseumnida | 살았어요 sarasseoyo | 살았어 sarasseo | 살았다 saratda |
| Future — 겠 (will/intend) | 살겠습니다 salgetseumnida | 살겠어요 salgesseoyo | 살겠어 salgesseo | 살겠다 salgetda |
| Future — (으)ㄹ 거예요 | 살 겁니다 sal geomnida | 살 거예요 sal geoyeyo | 살 거야 sal geoya | 살 것이다 sal geosida |
| Negative — 안 (don't) | 안 삽니다 an samnida | 안 살아요 an sarayo | 안 살아 an sara | 안 산다 an sanda |
| Negative — 못 (can't) | 못 삽니다 mot samnida | 못 살아요 mot sarayo | 못 살아 mot sara | 못 산다 mot sanda |
| Negative — long 지 않다 | 살지 않습니다 salji anseumnida | 살지 않아요 salji anayo | 살지 않아 salji ana | 살지 않는다 salji anneunda |
| Imperative | 사십시오 sasipsio | 사세요 saseyo | 살아 sara | 살아라 sarara |
| Propositive (let's) | 삽시다 sapsida | 살아요 sarayo | 살자 salja | 살자 salja |
Notice how the drop rule sorts the columns automatically: the ㄹ vanishes in 삽니다, 사세요, 사십시오, 산다, 삽시다 (endings in ㅂ/ㅅ/시/ㄴ) but survives in 살아요, 살았어요, 살겠어요, 살자 (endings in 아/ㄱ/ㅈ). You are not memorizing a scrambled paradigm — you are applying one rule per cell.

| Attributive — present | 사는 | saneun | drops (before ㄴ) |
| Attributive — past | 산 | san | drops (살 + ㄴ) |
| Attributive — prospective | 살 | sal | ㄹ merges (살 + ㄹ) |

| Nominal — gerund | 살기 | salgi | stays (before ㄱ) |
| Nominal — fact/nominal | 삶 | sam | ㄹ + ㅁ → 삶 [삼] |

The subtlety worth slowing down for: -(으)면 vs -(으)니까
Both -(으)면 ("if") and -(으)니까 ("because") belong to the 으-family, yet the ㄹ behaves oppositely in each — and this is where learners most often stumble:
- -(으)면: the 으 is blocked (ㄹ-stems never take it), but the ending then begins with ㅁ, which is not a trigger, so the ㄹ stays → 살 + 면 → 살면.
- -(으)니까: the 으 is blocked, and the ending then begins with ㄴ, which is a trigger, so the ㄹ drops → 살 + 니까 → 사니까.
시내에 살면 진짜 편해요.
sinae-e salmyeon jinjja pyeonhaeyo
If you live downtown, it's really convenient. (ㄹ kept: 살면)
Regular, not irregular
It is worth being precise about the class, because the fear is unearned. The true irregular verbs — the ㅂ, ㄷ, ㅅ, 르, ㅎ classes — are lexical: some verbs follow the pattern and others spelled identically do not, so you memorize membership verb by verb (돕다 is irregular → 도와요, but 잡다 is regular → 잡아요). The ㄹ-drop is nothing like that. Every ㄹ-stem drops in exactly the same environment; there are no exceptions to learn. It is a phonological reflex, closer to English "a → an before a vowel" than to "sing → sang." That is why 살다 sits here in the regular paradigms, with only a cross-reference to the genuinely different ㄹ-irregular attributive behavior. Treat the drop as automatic and it costs you nothing.
Common Mistakes
1. Keeping the ㄹ in the formal -ㅂ니다. ㅂ is a trigger; the ㄹ drops and the ㅂ becomes the batchim.
❌ 저는 서울에 살습니다.
Wrong — 살다 loses its ㄹ before -ㅂ니다: 삽니다.
✅ 저는 서울에 삽니다.
jeoneun Seoure samnida
I live in Seoul. (formal)
2. Inserting the 으 buffer. ㄹ-stems never take 으 — they drop or keep the ㄹ instead.
❌ 저 사람 이름 알으세요?
Wrong — no 으 on a ㄹ-stem; the ㄹ drops → 아세요.
✅ 저 사람 이름 아세요?
jeo saram ireum aseyo?
Do you know that person's name? (알다 → 아세요)
3. Dropping the ㄹ before -(으)면. Here the ㄹ stays; only the 으 is blocked.
❌ 여기 사면 편해요.
Wrong — 사면 is from 사다 'to buy'; 살다 'to live' keeps the ㄹ → 살면.
✅ 여기 살면 편해요.
yeogi salmyeon pyeonhaeyo
If you live here, it's convenient.
4. Keeping the ㄹ in the present attributive. ㄴ is a trigger, so 사는, not ×살는.
❌ 제가 살는 집이에요.
Wrong — 살다 drops its ㄹ before -는: 사는.
✅ 제가 사는 집이에요.
jega saneun jibieyo
It's the house I live in.
Key Takeaways
- 살다 models the ㄹ-stem class (알다, 만들다, 놀다, 열다): stem 살-, harmony 아.
- The stem ㄹ drops before ㄴ · ㅂ · ㅅ · 시 (삽니다, 사세요, 사는, 산다, 사니까) and stays everywhere else (살아요, 살고, 살면, 살자, 살던).
- A ㄹ-stem never inserts 으: 살면 / 사니까, never ×살으면 / ×살으니까.
- Watch -(으)면 vs -(으)니까: 면 keeps the ㄹ (살면), 니까 drops it (사니까).
- This is a fully regular elision, not one of the memorize-by-verb true irregular classes.
