There are many types of constructions in languages. And two approaches are proposed to explain these constructions. The one is rule-based approach, and the other is non-rule-base approach, for example Construction Grammar. Adopting former approach, this paper proposes that a syntactic variation can be the cause of construction formation. To clarify this idea, constructions are grouped into three types: a normal construction type, a quasi normal construction type, and a non-normal construction type. In these cases, ‘normal’ means ‘rule obeying’ or ‘can be formed by rules’. Furthermore, three Korean constructions, such as verbal reduplication construction, ‘geoss-i-da’ construction, and embedded conjunction construction, are examined to check the main proposal.
