Phonological changes are called weakenings when they are steps on the natural path that leads to deletion. (b) Weakening is something that happens to both consonants and vowels but in different ways. So we’ll look at the two cases separately 1 2 Consonant Weakening t tt t D ∅ T Figure 1: The scale of weakening 2 Degemination tt t t D Frication t T t t Voicing T D Deletion D ∅ Figure 2: Weakening processes 3 Weakening Early Late Gloss Degeminaton (tt > t) mittere, L meter,S ‘put’ ¯¯ ¯ Voicing (t > d) m¯at¯urus, L maduro,OS ‘ripe’ ¯ ¯ Frication (d > D) maduro, OS maduro[D], S ‘ripe’ ¯ ¯ Deletion (d > ∅) maDyr, OF mˆur[myK],F ‘ripe’ Figure 3: Consonant weakening in Romance (L = Latin, OS = Old Spanish, OF = Old French, F = French, S = Spanish) 4 3 Vowel Weakening The main process leading up to vowel deletion is vowel reduction, which generally means centralizing a vowel, which generally means turning it into @, see Figure 4. This usually happens to unstressed vowels. i u e @ a o Figure 4: Vowel reduction There are two sorts of vowel deletion.
