Abstract
This study investigated the frequency and combination patterns of hyphenated compound adjectives in two newspapers (The Japan Times and New York Times). The frequency of hyphenated compound adjectives in the two newspapers was counted based on their categories.Additionally, the hyphenated compound adjectives extracted from the newspapers were compared with the list of word combination patterns to clarify their formation. The results showed that the hyphenated compound adjectives were most frequently observed in the culture section.The most prevalent combination was noun + past participle. Furthermore, two novel word combination patterns were found: verb + past participle, adjective + adverb.
