<strong>contrastive</strong> features to the stem-f<strong>in</strong>al /t/ when it is word f<strong>in</strong>al and when it is<br />

word medial. 25<br />

A second condition that could be plausibly put on a <strong>contrastive</strong> doma<strong>in</strong> is<br />

that it should correspond to a category that has <strong>in</strong>dependent existence <strong>in</strong> the<br />

grammar. This condition would rule out arbitrary doma<strong>in</strong>s such as, for English,<br />

the set of consonants that could precede the sequence ___et ( pet, vet, Tet, debt, set,<br />

net, yet, get etc.) with<strong>in</strong> a word.<br />

<strong>The</strong> conditions for hav<strong>in</strong>g separate <strong>contrastive</strong> doma<strong>in</strong>s for evaluat<strong>in</strong>g<br />

vowels are met <strong>in</strong> Romance languages that dist<strong>in</strong>guish between stem vowels and<br />

des<strong>in</strong>ential vowels. Des<strong>in</strong>ential vowels occur <strong>in</strong> a closed class of suffixes and do<br />

not alternate with stem vowels. Moreover, stems and des<strong>in</strong>ences constitute<br />

important grammatical categories <strong>in</strong> such languages. Dyck (1995) and Frigeni<br />

(2003) argue that <strong>contrastive</strong> specifications must be assigned separately to<br />

25 <strong>The</strong> assumption that morphemes have a unique lexical form is not universally held. In theories<br />

that permit multiple lexical representations the concept of a phonological <strong>in</strong>ventory would have<br />

to be rethought along with what constitutes a permissible <strong>contrastive</strong> doma<strong>in</strong>.<br />

Keep<strong>in</strong>g now to the pr<strong>in</strong>ciple that morphemes have unique underly<strong>in</strong>g forms, it may still<br />

be the case that children at early stages of acquisition may not yet relate different forms of<br />

morphemes. For example, they may have different lexical representations for the f<strong>in</strong>al consonant<br />

<strong>in</strong> write and the medial consonant <strong>in</strong> writer (s<strong>in</strong>ce writer is not yet decomposed <strong>in</strong>to separate<br />

morphemes it is not accurate to label the t <strong>in</strong> writer as ‘stem f<strong>in</strong>al’ for these learners). It follows<br />

that child grammar may have separate sub-<strong>in</strong>ventories and <strong>contrastive</strong> doma<strong>in</strong>s that would not<br />

be permitted <strong>in</strong> the adult grammar.<br />
