Transcript of AY12/13 EL1101E Tutorial 6: Allomorphy
http://www.upodn.com/ Describe the environment in which each allomorph appears. Task 3 Choose one of the forms of the plural suffix as the basic form, and write a morph-phonological rule that changes it into the other forms in the appropriate contexts. Task 1 Consider the plural form of each of the following nouns. Transcribe (using IPA symbols) the sound(s) in the plural suffix on each word. Task 2 You should have found three different possible plural suffixes; their distribution is predictable based on the sounds in the words they attach to. Explain the distribution of these three suffixes. (Hint: you might want to make a table of sounds appearing near each suffix) Task 1 Task 3 Propose a morpho-phonological rule that derives the different realizations (allomorphs) of the past-tense morpheme from an underlying morph. Task 2 Of the three realizations of the past tense morpheme you identified in task 1, which one would you take to be the underlying morph? Explain your answer. English past tense The past-tense morpheme ‘–ed’ can be pronounced in three different ways. Based on the pronunciation of the past tense morpheme, divide the following words into three groups. Provide a phonetic transcription for each instance of the tense morpheme. The past tense morpheme, “-ed,” is pronounced in three different ways: Recap! What is an allomorph? An allomorph is a variant form of a morpheme.
Occurs when a unit of meaning can vary in sound without changing meaning.
Explains the phonological variations for specific morphemes Accurate as a representation in the Singaporean context? Revised version! /d/ is the underlying morph.
It has the widest distribution.
Appears elsewhere other than after alveolar stops and voiceless sounds. English plural allomorphs Phonetic Transcription
(-tense morpheme) The morpheme 'bomb' in English There are two allomorphs.
[bamb] Our initial answer:
[bamb] appears when there is a stressed vowel after the morpheme (though not necessarily directly after it).
[bam] appears when no stressed vowel follows the morpheme.
Class discussion/Dr Derek's answer:
[bamb] is the underlying morph.
[bam] appears when there is a stress in the first syllable of a word. (*Note: Monosyllabic words are all stressed by default.)
[bamb] appears when there is a stress in a syllable elsewhere other than the first.
