This study conducts a sociolinguistic analysis of coordinate word order in Korean. The results can be summarized as follows: (i) Word placement (P1, P2) of coordinate word order is determined by the elements of lexical hierarchy, basic vocabulary, word frequency and sociocultural meaning. The elements of lexical hierarchy, basic vocabulary, and word frequency designate the status along the familiar-estranged and superior-inferior axes. (ii) The primary types of coordinate word order are divided into right order (pattern A) types and counter order (pattern B) types. Further, these are based on the arrangement of affirmative meaning (Af) and negative meaning (Ne), which are in accordance with word placement and the sociolinguistic rules of the alternative rule and co-occurrence rule. (iii) The environment types of coordinate word order include natural word order, social word order, and belief word order. The types of word order use include freezing word order and situational order. Therefore freezing word order and situational order, combined with right order and counter order, constitute the formation rule of word order. Based on our saram/horaŋi (man and tiger) example, we describe the input and output of word order. (iv) Coordinate word order comprises different types of word order use, which are influenced by gender variety. Further, the pooling of word order types forms a sociolinguistic pattern and a V-shaped curve. There is also generation variety, which also allows for sociolinguistic patterns to be formed through pooling. The criteria for a W-shaped curve are bi-order, right word order, and counter word order, which combine to form an age-grading and undulating pattern. Finally, there is class variety. In rural dialects class references are used. High classes use the right word order of new types, while low classes use the right word order of old types.
