This paper investigates the syntactic and semantic features of the construction ‘V -go Siphta' in Korean. The construction ‘V-go Siphta' manifested in forms such as ‘NP2 Ul/Lul V-Ko Siphta' and ‘NP2 I/Ka V-go Siphta' has been a subject of debate. To elucidate the similarities and peculiarities of these ‘V-go Siphta' constructions, an analysis was first conducted on the distinguishing features between ‘NP2 Ul/Lul' and ‘NP2 I/Ka'. Both function as essential components of a sentence, indicating the object. However, ‘NP2 I/Ka' exhibits similarities to an object complement in its difficulty to separate from the predicate. In the case of ‘NP2 I/Ka V-go Siphta', the ‘Siphta' has properties similar to an affix. Based on this analysis, corpus searches revealed that when the verb ‘V' corresponds to sensory verbs such as ‘Mekta' (to eat), ‘Pota' (to see), and ‘Tutta' (to hear), the construction ‘NP2 I/Ka V-go Siphta' is more prevalent than ‘NP2 Ul/Lul V-go Siphta'. Verbs that effectively reflect human desires and longings are more likely to be combined with ‘-go shifta' to develop into psychological adjectives. Thus, while the ‘-go-sifta' structure can function as an auxiliary verb structure, it can also function as a psychological adjective in sentences containing verbs that reflect physiological and primal desires. Therefore, in this paper, we propose two types of syntactic structures to explore further.
