constra<strong>in</strong>ts and co-occurrence restrictions are sufficient to exclude nonexistent<br />

vowels and to ensure that vowels present <strong>in</strong> the <strong>in</strong>ventory will surface faithfully.<br />

(7.32).<br />

(7.31) Constra<strong>in</strong>t rank<strong>in</strong>g for Nez Perce (Bakovic@ 2000)<br />

*[+back, +ATR] & IO-ID [ATR], IO-ID [low], *[–back, –ATR] >> IO-ID<br />

[bk] >> *[–high, +ATR], *[+high, –ATR] >> IO-ID [high] >> *[+back,<br />

+ATR] >> *[–low, –ATR] >> IO-ID [ATR]<br />

Look<strong>in</strong>g only at the faithfulness constra<strong>in</strong>ts, we f<strong>in</strong>d the <strong>hierarchy</strong> <strong>in</strong><br />

(7.32) Rank<strong>in</strong>g of faithfulness constra<strong>in</strong>ts (Bakovic@ 2000)<br />

IO-ID [low] >> IO-ID [back] >> IO-ID [high] >> IO-ID [ATR]<br />

This constra<strong>in</strong>t <strong>hierarchy</strong> translates <strong>in</strong>to an ill-formed <strong>contrastive</strong> <strong>hierarchy</strong><br />

(7.33). Features written under the phonemes are redundant.<br />

(7.33) Contrastive <strong>hierarchy</strong> based on (7.32)<br />

[+low] [–low]<br />

[–back] [+back] [–back] [+back]<br />

<strong>The</strong> feature [ATR] is phonologically redundant <strong>in</strong> this <strong>hierarchy</strong>, though it<br />

is the active feature <strong>in</strong> vowel harmony. It is redundant <strong>in</strong> the [–low] vowels<br />

because of the presence of [high], which does not appear <strong>in</strong> the <strong>contrastive</strong><br />
