Assimilation is an articulatory process that involves " the variation in the phonetic manifestation of a given sound due to its taking of some of the features of nearby sounds" (Ohala,1993:156). It is attested cross-linguistically and it is ascribed to economy in efforts or ease of articulation (see among others, Abercrombie,1967: 135 and Bakovi, 2006). The study of assimilation has received great attention in phonology over the last century and a renewed interest in assimilation in recent phonological studies is remarkably reflected in the sum of works written about it. Many phonologists have embarked on describing assimilation patterns and providing detailed accounts of its types and characteristics (see among others, Abercrombie, 1967:133-9; Roach, 2000:110-113; 2001: 53-61; McCarthy and Smith, 2003: 320-323). Many of these studies have focused on differentiating between diachronic (historical) and synchronic assimilation, whereas others have, more specifically, embarked on establishing the aspects of this change, among of which are: the direction of change: regressive or progressive, the degree of assimilation: partial or complete, the sounds features influenced by this change: voicing, place or manner of articulation, etc.
