Nty ＞ nts ＞ us: cantiōnem ＞ cansọ, comĭn(i)tiāre ＞ comensar, sperantia ＞ esperansa. Purely learned words have nti: essentia. Cf. Nc´y.
Ny ＞ n´: extraneum ＞ estranh, tĕneo ＞ tenh, vĕniat ＞ venha. Before or during the literary period final n´ or n´s lost its palatal quality in many dialects: ingĕnium ＞ genh gen. If estraniar comes from extraneāre (and not from ✱extranicāre), it must be a word of later adoption; so estrangier. In sotran ＜ subterraneum there is probably a change of suffix.
Pry probably became regularly bry: capreŏlum ＞ ✱cabriǫl cabirǫl (cabrǫl seems to be a new formation from cabra). Coyre ＜? cŭpreum is unexplained.
Pty ＞ ts, which, when it remained medial, was reduced, before and during the literary period, to s: ✱captiāre ＞ cassar, ✱corrŭptiāre ＞ corrossar, nĕptia ＞ nęssa, ✱nŏptias (§ [38], 2) ＞ nǫssas. Cf. C´y.
Py remained py in the west and a part of the south, and elsewhere became ptš, later tš: apium ＞ ache api, ✱apprŏpiat (＜ prŏpe) ＞ aprǫpcha aprǫcha aprǫpia, sapiam ＞ sapcha sacha sapia, sapiĕntem ＞ sachent sapient, sēpia ＞ sẹpia. Asabentar is from sabẹn. Piion ＜ pipiōnem is French. Learned words have pi: copia; but mancĭpium ＞ mancip massip.
Rc´y ＞ rts (＞ rs?): urceŏ́lum (Zs., XXVI, 668) ＞ orzǫl.
Rdy ＞ rdz: ✱dis-tardiat ＞ destarza. Ordi = hŏrdeum is perhaps from the genitive hŏrdeī, as in tres modii hordei, etc.
R-g ＞ rdž: clĕrĭcus ＞ clęries.
Rg´ ＞ rdž and rdz (＞ rz): argĕntum ＞ argen, ✱burgē(n)sis ＞ borgẹs borzẹs (also borgues, under the influence of borc), ✱dē-ērĭgit ＞ dẹrs, ✱dē-ē(i)gĕre ＞ dẹrzer (also derdre: § [71]), sŭrgĕre ＞ sọrger sọrzer, sŭrgit ＞ sọrtz.
Rny ＞ rn´: ✱Arvĕrnium ＞ Alvęrnhe.
