participate <strong>in</strong> voic<strong>in</strong>g alternations just the way other obstruents do. In particular,<br />

there is a rule of regressive voic<strong>in</strong>g assimilation (RVA) that assimilates all<br />

obstruents <strong>in</strong> a cluster to the voic<strong>in</strong>g of the f<strong>in</strong>al obstruent <strong>in</strong> the cluster. Halle’s<br />

formulation (1959: 64) is given <strong>in</strong> (4.13).<br />

(4.13) Regressive voic<strong>in</strong>g assimilation (Halle 1959)<br />

Rule P 3a. If an obstruent cluster is followed by a [phrase]<br />

boundary or by a sonorant, then with regard to voic<strong>in</strong>g the cluster<br />

conforms to the last segment…<br />

Halle observes that <strong>in</strong> the prevail<strong>in</strong>g neo-Bloomfieldian theory the rule of<br />

RVA would have to apply twice: once <strong>in</strong> the morphophonemic component,<br />

where the result is an exist<strong>in</strong>g phoneme (4.14a); and aga<strong>in</strong> at the phonemic level<br />

to create voiced allophones of the unpaired phonemes /ts, tS, x/ (4.14b).<br />

(4.14) Russian regressive voic<strong>in</strong>g assimilation apply<strong>in</strong>g twice<br />
