This paper aims to elaborate on the form and meaning of the -(u)n nameci construction. The following summarizes our discussion. First, the -(u)n nameci construction is a construction in which the preceding clause indicates the cause and the following clause indicates the effect. Only -(u)n nameci is fixed, the preceding and following clauses are slots. Therefore, the -(u)n nameci construction can be called a 'causal schematic construction'. Secondly, the causal relationship represented by the -(u)n nameci construction is different from ordinary causal relationships, indicating special meanings such as 'deepening of degree', 'anti-expectation', and 'extremity'. The frequent appearance of deepening expressions such as adverbs of degree, expressions of unexpectedness(-ko mal-, -e peli-, and kuman, etc.), and focus particles indicating extremity like kkaci, man in the -(u)n nameci construction demonstrates that the form and meaning of the -(u)n nameci construction are interrelated.
