1. Saupes apparently belongs to a dialect in which au prevented voicing. Cf. § [65], P, 3.
Rw > rgw > rg: mĕruit > męrc.
Sw seems to have been reduced early to s in consuetūdĭnem ✱costūmen > costüm (costüma). Cōnsŭo apparently became ✱cōsio, whence an infinitive ✱cōsĕre or ✱cosīre (Pr. cǫzer, cosir).
Tw > dw > gw > g: pŏtuit > pǫc.
1. Ba(t)tuo, qua(t)tuor were reduced to batto, ✱quattor in Vulgar Latin: Pr. bat, quatre.
5. Groups Ending in Y.
73. This class contains: 1st, combinations of consonant + y < e̯ or i̯, cf. § [40], (2); 2d, consonant + g´ > y (§ [55], G), the g´ having been in some cases always contiguous to the preceding consonant, in others originally separated from it by a vowel; 3d, consonant + g > y, the g representing an original c or g between the last two vowels of a proparoxytone, cf. § [65], G, (3). It does not include dy and gy, which early became y: see § [65], Y. See § [63], (1). The groups will be considered in alphabetical order:—
Bry > bry in ebriācum > ebriac (iure is probably French).
βy was early reduced to y in habeo habeam etc. and dēbeo dēbeam etc., partly, no doubt, through the proclitic use of these words, partly under the influence of audio > ✱auyo audiam > ✱auya and video > ✱veyo vĭdeam > ✱veya; this y, like any other medial y (§ [65], Y), became džy̆ or remained y: ai (for some reason there seems to have been no form ✱ach), aia; dẹi dẹch, dẹia. Aside from these words, βy > udž and uy apparently in the north; elsewhere uy, by, vy—uy prevailing in the west, by and vy in the south and east. When the y became final, it changed to i, which, after a consonant, was syllabic. Ex.: abbrĕviat > abręuia, ✱aggrĕviat > agrẹuia, allĕviat > alęuia, avĭŏ́lum > aviǫl aiǫl, cavĕa > gabia cauia, labia > lavia-s, ✱leviarius > leugięrs, ✱rabiam (= rabiem) > rabia rauia,[67] ✱rabiāre > rabiar, rabiōsus > rabiọs rauiọs, rŭbeum > rọg rọi,[68] ✱sabium > savi sabi, atavia > tavia, vidŭvium > vezọig bedọi.[68] In purely learned words, Latin bi, vi, etc., are kept: abiurament, fluvial. Brĕvio > bręy: cf. § [65], β, 3.
