Gada 가다 : the basic form of "go" Boda 보다 : .... of "see/look" (The letter or syllable in square brackets is the key that you can make the tense you want to, the romanization would help you see how to pronounce.) Ga[n] da 간다 : the present tense Bo[n] da 본다 Ga[go it 고 있]da 가고 있다(Gago it-tta) : the present progressive tense Bo[go it ...]da 보고 있다(Bogo it-tta) Ga[go it eot 고 있었]da 가고 있었다(Gago it-sseot-tta) : the past progressive tense Bo[go it eot ...]da 보고 있었다(Bogo it-sseot-tta) Ga[t ㅆ] da 갔다(Gat-tta): the past tense Bo[at 았] da 보았다(Bo-at-tta) →B[wat 왔] da 봤다(Bwat-tta) 봤다 is the abbreviation for 보았다. 봤다 is used in spoken Korean. When you make 'oda ㅗ다' verbs like oda 오다 come, nolda 놀다 play, dolda 돌다 turn : The letter before 'da 다' ending with the final consonant ⇒ Add [at 았] in front of 'da 다' ... ending with the vowel ⇒ 오다-왔다, 보다-봤다 ; I assume there're no more this kind of verbs. There are some more irregular verbs like those verbs above. Ga[t eot ㅆ었] da 갔었다(Gat-sseot-tta) : the present/past perfect tense B[wat eot 왔었] da 봤었다(Bwat-sseot-tta) Hope this helps.

present : 나는 학교에 간다. (I go to school.) progressive present :나는 학교에 가고 있는 중이다.(I am going to school.) past : 나는 학교에 갔었다.(I went to school.) future : 나는 학교에 갈 것이다.(I will go to school.)

well from what i've got... there's like, a root to all verbs. in gada, the root is ga. and this stays the same no matter what kind of suffix or conjugation or whatever you call it. there's a lot of ways... ga~ ~go ittda = ...ing ~il goshida = future tense ~tt da = past tense an ~n da= negative tense i think. ^^; there's also "GAJIMA~!!" (don't go!!) which is just one i remember. lol also if the root ends in a vowel sound or a consonant sound, it messes with the different ways you can add suffixes. like in deudda--to hear. (i wish i could write korean words in text...) deud is the root. deul eottda=past tense deud ji-anh-neunda= negative also, there's the DA at the end. if you change DA to JA then it's like "lets..." there's so much more i could try and get into...but i don't think i should say too much cuz i'm still trying to get it straight in my own head!! XD i hope this helps....did i get it right??

went(=갔었다=got sserr dda) let's go(가자=ga za) I am 'going' to school(=나는 학교에 "가는중이다 or 가고있다") -> ('ga noon joong e da' or 'ga go it da)
