“…Early efforts, like Bahns and Wode (1980), argue that consideration of linguistic forms without consideration of the functions those forms realize and how those relations might change during acquisition fails to capture critical observations about the development of an interlanguage. Very much the same message can be found in more recent efforts (Fuller & Gundel, 1987;Gass, 1986;Gundel, Stenson, & Tarone, 1984;Gundel & Tarone, 1985;Hanania & Gradman, 1977;Huebner, 1979Huebner, , 1983Jordens, 1980;Lightbown, 1983;Meisel, 1987;Pfaff, 1987;Tomlin, 1984Tomlin, , 1987Trevise, 1987;Trevise & Porquier, 1986;Veronique, 1987). The Nijmegen-based European Project (Perdue, 1984) embraces relational functional description as one of its principal goals (Klein & Perdue, 1988).…”
