Although the most accessible computer implementations (Koskenniemi, 1983; Antworth, 1990; Karttunen, 199a) of finite-state morphotactics have been limited to building words via the concatenation of morphemes, the theory itself does not have this limitation. In Semitic morphotactics, root and pattern morphemes (and, according to one's theory, perhaps separate vocalization morphemes) are naturally formalized as regular languages, and stems are formed by the intersection, rather than the concatenation, of these regular la.nguages. Such analyses have been laid out elsewhere (Kataja and Koskelmiemi, 1988; Beesley, 1998a: Beesley, 19981) ) and cannot be repeated here. For present t)urt)oses, it will suffice to view morl)hophonelnic (underlying) stems as being formed from the intersection of a root and a pattern, where patterns contain vowels and C slots into which root radicals are, intuitively speaking, \"plugged\", as in the following Form I perfect active and passive verb examples.
