Flashcards in Morphophonemics Deck (6)
-variant forms of a morpheme
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/)
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
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)
