“…It is widely accepted that the phonetic, or surface, word in Semitic languages such as Arabic and Hebrew is made up of at least two abstract underlying morphemes, the word pattern and the root (e.g., Glinert, 1996;Hilaal, 1990;Holes, 1995;Idrissi, Prunet, & Béland, 2008;Versteegh, 1997;Wright, 1995; though see Berent, Vaknin, & Marcus, 2007;Ratcliffe, 2004;Ussishkin, 1999Ussishkin, , 2005, for alternative stem-based views). The root is exclusively consonantal (e.g., in Arabic {frq}, {dðr}, and in Hebrew {drx}, {khl}), while the word pattern consists of vowels and a subset of consonants (e.g., {fa latun}, {maf alun} in Arabic and {Hif il} in Hebrew), where the letters ''f l'' are place holders for the first, second, and third root consonants.…”
