While many findings of the three-pattern prosodic systems in both Ryukyuan and Japanese dialects have recently been achieved, this study focuses on the systems of the Okinoshima archipelago, which have long been reported to have three-pattern prosodic systems since back in the 1950s. Especially focusing on compounds of the Goka dialect in Okinoshima, the study shows that the basic prosodic rule for its compounds is the one in which the pattern of their ‘first’ members is preserved as the patterns of their compounds, and that all the exceptions to this rule appear as Pattern A. Based on this observation, the paper concludes that the most productive pattern in the compounds in Goka is Pattern A, while Pattern B the least productive. The paper further argues, referring to the prosodic patterns of loanwords, that the productivity of Pattern A in compounds may be due to the general tendency of the prosodic system of this dialect, in which the longer the word is, the more productive Pattern A becomes, while just the opposite tendency is observed for Pattern B.
