1. Sentence-final endings Verbs are the most complex part of speech in Korean. Their structure when used as the predicate of a clause is prefix + root + up to seven suffixes, and can be illustrated with a template: (negative prefix) + ROOT + (valency) + (honorific) + (tense-aspect) + (formality) + (syntactic mood) + (pragmatic mood) + (polite) - The negative prefix is 안 "not"; the word 못 "can't" also occurs in this position. - ROOT is a verb stem like 알(다) 먹(다) - valency may be passive or causative passive suffix : -이-, -히-, -리-, -기- causative suffix: -이-, -히-, -리-, -기-, -우-, -구-, -추-, -애-, -이우-, -시-, -으키-, -이키- - honorific suffix : -시- - tense-aspect Future tense & prospective aspect : -겠- past perfective : -었/았- remote past : -었었/았었- past-future : -었겠/았겠- remote past-future : -었었겠/았었겠- - formal suffix : -ㅂ,습,읍- - syntactic mood indicative : -는,니,ㄴ- retrospective : -던,디,ㄷ- - pragmatic mood declarative : -다,라,에- interrogative : -까,야,가- propositive : -다,자,에- imperative : -오,어라/아라,게- - polite suffix : -요 2. Attributive Endings Attributive verb endings modify nouns and take the place of attributive adjectives. Korean does not have relative pronouns. Instead, attributive verbs modify nouns, as adjectives do in English. (negative prefix) + ROOT + (valency) + (tense) + (attributive) - attributive Present progressive : -는 Perfective : -은/ㄴ Imperfective : -던 Future : -을/ㄹ 3. Conjunctive Endings Verbs can take conjunctive suffixes. These suffixes make subordinate clauses. - conjunctive suffix : -고,(어/아)서,면,거나,기도,든지 Refer to http://en.wikipedia.org/wiki/Korean_verbs
