If -(으)ㄴ 적이 있다 is the careful, résumé-style way to say "I have the experience of…," then -아/어 봤다 is the way you actually say it over coffee. It is the auxiliary -아/어 보다 ("try doing, give something a go") in its plain past form, and it means "I've tried it / I've done it (once)." 김치 먹어 봤어요? — "Have you tried kimchi?" — is the phrase you will hear and use constantly. This page shows how it is built, how it differs from 적이 있다, and the one trap that catches every English speaker: the 봤 here has nothing to do with the verb "to see."
How it's built: -아/어 보다 in the past
Take any action verb, put it into its -아/어 connective form (the same form you use before -요, -서, -도), and add 보다. Then conjugate 보다 for tense. The past is 봤다, from 보- + -았- with the vowels contracting: 보 + 았 → 봤.
김치 먹어 봤어요?
gimchi meogeo bwasseoyo?
Have you tried kimchi?
제주도에 가 봤어요.
Jejudo-e ga bwasseoyo
I've been to Jeju (I've actually gone and seen it).
그 책 읽어 봤어요.
geu chaek ilgeo bwasseoyo
I've read that book (I gave it a go).
The -아/어 part follows ordinary vowel harmony: bright-vowel stems (with ㅏ or ㅗ) take -아, everything else takes -어, and 하다 becomes 해. So you get 가 봤다, 먹어 봤다, 읽어 봤다, 들어 봤다, and 해 봤다.
| Verb | -아/어 form |
| Meaning |
|---|---|---|---|
| 가다 | 가 | 가 봤다 | have been / gone |
| 먹다 | 먹어 | 먹어 봤다 | have tried (eating) |
| 하다 | 해 | 해 봤다 | have tried (doing) |
| 듣다 (ㄷ-irreg.) | 들어 | 들어 봤다 | have heard / listened |
| 입다 | 입어 | 입어 봤다 | have tried on |
이 스웨터 한번 입어 봤어요.
i seuweteo hanbeon ibeo bwasseoyo
I tried this sweater on.
스키 타 봤어요?
seuki ta bwasseoyo?
Have you (ever) skied?
그 노래 들어 봤어요.
geu norae deureo bwasseoyo
I've heard that song.
The auxiliary 보다 is not "to see"
Here is the trap. 보다 as a main verb means "to see / watch." But in -아/어 보다 it is a grammaticalized auxiliary meaning "do X and see how it goes → try X." When you say 먹어 봤어요, you are not saying "I saw someone eat"; you are saying "I tried eating (it) — I gave it a taste." The eating is the real action; 보다 just adds the "give it a go, sample it" flavor.
이 소스 좀 찍어 봤어요.
i soseu jom jjigeo bwasseoyo
I tried dipping it in this sauce.
한국 노래를 불러 봤어요.
Hanguk noraereul bulleo bwasseoyo
I gave singing a Korean song a try.
-아/어 봤다 vs -(으)ㄴ 적이 있다
Both express experience, and they overlap heavily. The difference is one of feel and emphasis:
- -아/어 봤다 is colloquial and foregrounds having actually tried or sampled something. It is warm, everyday, and slightly more concrete: "I've given it a go."
- -(으)ㄴ 적이 있다 is neutral and structural — "there was an occasion." It sounds a touch more formal or bookish and states the plain fact of experience. (See -(으)ㄴ 적이 있다/없다.)
For the strongest, most idiomatic experiential, Koreans stack the two: -아/어 본 적이 있다, literally "there is an occasion of having tried."
번지점프 해 봤어요.
beonjijeompeu hae bwasseoyo
I've done a bungee jump (I tried it).
번지점프 해 본 적이 있어요.
beonjijeompeu hae bon jeogi isseoyo
I have (the experience of having) done a bungee jump.
The first is what you'd say to a friend; the second adds a shade of "on the record, in my life, this has happened." Neither is more correct — they sit at slightly different points on the casual-to-neutral scale.
Don't confuse it with the invitation -아/어 보세요
The non-past imperative -아/어 보세요 ("give it a try / go ahead and do it") looks almost identical but does a completely different job: it invites the listener to try, rather than reporting your own experience. Keep the tenses apart.
이거 한번 드셔 보세요.
igeo hanbeon deusyeo boseyo
Please give this a try. (invitation, honorific 드시다)
네, 아까 먹어 봤어요.
ne, akka meogeo bwasseoyo
Yes, I already tried it a moment ago. (report of experience)
When plain past is better: the "sampling" nuance
Because -아/어 봤다 adds "gave it a go / sampled it," it is slightly wrong for routine or unremarkable actions. "I ate breakfast this morning" is just 아침 먹었어요 — you weren't sampling breakfast. Reserve 봤다 for things you tried, especially first-time or exploratory experiences.
오늘 아침 먹었어요.
oneul achim meogeosseoyo
I had breakfast this morning. (routine — plain past)
새로 생긴 그 식당 가 봤어요.
saero saenggin geu sikdang ga bwasseoyo
I checked out that new restaurant (I gave it a try).
Common Mistakes
1. Getting the vowel harmony wrong. ㅓ, ㅜ, ㅡ, ㅣ stems take -어, not -아.
❌ 먹아 봤어요.
meoga bwasseoyo
Wrong harmony — 먹 is a dark-vowel stem.
✅ 먹어 봤어요.
meogeo bwasseoyo
I've tried it (eating).
2. Failing to contract 하다 → 해. A 하다 verb becomes 해 봤다, never ×하 봤다.
❌ 청소하 봤어요.
cheongsoha bwasseoyo
Wrong — 하다 contracts to 해.
✅ 청소해 봤어요.
cheongsohae bwasseoyo
I gave cleaning it a try.
3. Doubling 보다 to mean 'try watching.' ×봐 봤어요 (from 보아 봤어요) is avoided because it stacks 보다 on itself; use the plain past or 본 적 있다 instead.
❌ 그 드라마 봐 봤어요?
geu deurama bwa bwasseoyo?
Awkward — don't stack 보다 on 보다.
✅ 그 드라마 본 적 있어요?
geu deurama bon jeok isseoyo?
Have you (ever) seen that drama?
4. Confusing -아/어 보세요 with -아/어 봤어요. One invites; the other reports.
❌ 김치 먹어 보세요?
gimchi meogeo boseyo?
If you mean 'Have you tried kimchi?', this is wrong — it says 'Please try the kimchi.'
✅ 김치 먹어 봤어요?
gimchi meogeo bwasseoyo?
Have you tried kimchi?
5. Using 봤다 for ordinary, non-exploratory actions. The "sample it" flavor is wrong for routine events.
❌ 어제 잠을 자 봤어요.
eoje jameul ja bwasseoyo
Odd — implies you 'gave sleeping a try,' as if experimentally.
✅ 어제 잠을 잘 잤어요.
eoje jameul jal jasseoyo
I slept well last night.
Key Takeaways
- -아/어 봤다 = the auxiliary 보다 ("try / do-and-see") in the past = "I've tried / I've done (once)."
- The 봤 is not "saw" — the first verb carries the action, 봤다 adds "gave it a go / experienced it."
- It overlaps with -(으)ㄴ 적이 있다 but is more colloquial and concrete; stack them (-아/어 본 적이 있다) for the strongest experiential.
- Keep it apart from the invitation -아/어 보세요 ("please try") and from routine actions, which just take the plain past.
