Tl ＞ tl, which during the literary period became ll and then l: rŏtŭlum ＞ rǫtle rǫlle, spathūla ＞ espatla espalla espala. In really popular words tl had become cl in Vulgar Latin.[61]
Yl ＞ il: bajŭlus ＞ bailes. Cf. § [65], Y, (1).
69. A group of three consonants remained unchanged, except that double consonants became single: ambulāre ＞ amblar, implēre ＞ emplir, avŭncŭlus ＞ avọncles, cĭrcŭlus ＞ cẹrcles, mascŭlus ＞ mascles, ✱afflammāre ＞ aflamar, inflāre ＞ enflar, ŭngŭla ＞ ọngla, emplastrum ＞ emplastre.
1. Selcle, beside cercle, seems to show an assimilation of the r to the l of the next syllable. Empastre, beside emplastre, has been influenced by pasta. Emblar is probably from V. L. ✱imbolare = involare.
3. Groups Ending in R.
70. The groups of two consonants will be treated in alphabetical order. It will be seen that br, gr, lr, nr generally remained unchanged; mr, sr, zr (and sometimes lr, nr) developed a glide consonant; cr, pr voiced, and βr, c´r, dr, tr, yr vocalized their first element.
Br ＞ br, also ur, occasionally ir (through ür): fabrum ＞ fabre faure[62], fĕbrem ＞ fębre fęure, lībra ＞ liura; Octōbrem ＞ ochọyre. For brg, see § [80].
βr ＞ ur, occasionally ir: bĭbĕre ＞ bęure, débēr’ hábḙo ＞ deβr’áyo ＞ deurái, ✱rōbŏrem ＞ rọure rọire; ✱mŏvĕre (= mŏvēre) ＞ mǫure, plŏvĕre ＞ plǫure.
Cr ＞ gr: acrem ＞ agre, lacrĭma ＞ lagrema, lŭcrum ＞ lọgre, macrum ＞ magre, sacrāre ＞ sagrar, sŏcrum ＞ sǫgre.[63] In late learned words we find cr: secret.
C´r ＞ ir: cŏcĕre ＞ cǫire, dīcĕre ＞ dire, dūcere ＞ düire, facĕre ＞ faire. Cf. § [49], (1).
