Allomorphy

-variant forms of a morpheme
-[e]/[en]
-[-s],[-z],[ez]

2

How are allomorphs represented in the mental lexicon?

-there are two phonetic forms, but one underlying form
-UR /pəɹmɪt-jən/ - PR [pəɹmɪʃn̩ ]
-Allomorphs whose relation is phonologically unpredictable stored as separate underlying representations:
o PR [ɡow]~[wɛnt], UR /ɡo/, /wɛnt/)

3

English plurals allomorphs

-alternation is phonologically predictable=allomorphs must share one UR
- [-s]: [-s] ~ [-z] ~ [-əz]
-[-s]:After non-sibilant voiceless consonants
-[-z]:After non-sibilant voiced consonants or vowels
-[-əz] (or [-ɪz]):After sibilants

4

Which of the allomorphs is the UR?

-allomorph that occurs in the widest set of environments is chosen to represent the UR of the morpheme (the assumption of economy: simpler rules are preferred)

5

Total Assimilation

completely assimilates

6

English past tense allomorphs

[-t] ~ [-d] ~ [-ed]
[-t]:ending in voiceless consonant (except /t/)
[-d]: ending in voiced consonants (except /d/) or vowels
[-ed] (or [-Id]): ending in alveolar stops
