Pairs that look alike, and are not

Near-synonym grammar, as this account uses the term, is a bundle of items that mean something so close that a learner is tempted to swap them. Error analysis collects the sentences learners actually produce, sorts them by type, and looks for a cause. Contrastive linguistics compares the two languages. Chinese is described as an isolating language: grammatical relations are shown by word order and function words, without changes of form. Korean is described as agglutinative: particles and endings are attached to a root. Because of that difference, omissions and substitutions of particles are said to be common among Chinese learners.

The work described here looked at 912 error sentences and divided them into particles and endings. Among particles, the subject markers 이/가 and the object markers 을/를 are often confused. 이 attaches after a consonant, 가 after a vowel; 을 and 를 follow the same condition. An intransitive verb, the text says, takes 이/가, a transitive verb 을/를, and a learner who does not yet know which verbs go with which markers will mix them. When an inanimate noun has the meaning of a group, the subject marker -에서 may appear instead. Teaching, the writer suggests, should present the function of the particle together with the kind of verb that accompanies it.

A reason, a contrast, and a guess

-아/어서 and -(으)니까 can both give a reason, but they do not behave the same way after that. -(으)니까 may be followed by an imperative or a hortative; -아/어서 may not. 비 와서 우산 가져가세요 is the error given for a speaker who has not yet learned that constraint. -지만 and -아/어도 also part company. When the first clause is a past, non-factual proposition, -지만 is constrained; -아/어도 cannot take a present or future tense in the following clause in the case described, and is constrained with -겠-, while -지만 is not. -지만 is also described as the more humble of the two.

A closing pair concerns a guess. 꽃병이 깨진 것 같습니다 is marked as acceptable. 꽃병이 깨졌나 봅니다 is marked as only marginally so, because -나 보다 can sound as if the speaker is not reflecting on a fault of their own; 것 같다, in this account, can carry a different kind of responsibility for a judgment. Teaching methods named include focus on form, input enhancement, and dictogloss — having a group reconstruct a text they have heard, so that attention falls on the form. The 912 sentences are left without a year attached.
