閩東區泰順三魁方言中 [ɵy] 韻至少有六個來源：*oe、*yoe、*iɔʔ、*uɔ、*uɔʔ、*uɔi。這種大規模韻母合併在閩東區方言中很少見。三魁方言音韻史上 (1) 以 *t 系和 *tʃ 系聲母為條件 *uɔ/uɔʔ 的細音化、(2) 介音＋半低元音變成單個半高元音、(3) 半高元音的複元音化以及 (4) *ʔ 尾入聲韻的舒聲化這四種語音演變結合起來促使形成 [ɵy] 韻。鄰近的泗溪方言的 [əy] 韻和筱村方言的 [yəu] 韻也是經歷了相似的語音演變過程而形成的韻母。

　　There are at least six proto finals which become the final [ɵy] in the Eastern Min Sānkuí dialect of Tàishùn County, namely *oe, *yoe, *iɔʔ, *uɔ, *uɔʔ, and *uɔi. Four main historical phonological backgrounds in combination brought about this rarely attested large-scale merger in Eastern Min, namely (1) the palatalization of the medial *uɔ/uɔʔ, conditioned by the initial *t group and *tʃ group, (2) the change of the medial + lower-mid vowel into a single upper-mid vowel, (3) the diphthongization of upper-mid vowels, and (4) the lengthening of the checked syllables with coda *ʔ. The final [əy] of the neighboring Sìxī dialect and the final [yəu] of the neighboring Xiǎocūn dialect are also formed through similar phonological development.
