“…The general consensus amongst many scholars is that subject RCs are essentially easier to acquire than non-subject RCs, based on the following: (a) subject RCs have been reported to emerge at an earlier developmental stage in naturalistic child language than non-subject RCs (e.g., Brandt, Diessel & Tomasello, 2008, Diessel, 2004Dissel and Tomasello, 2000) (b) the majority of experimental evidence suggests that children perform best on subject RCs in comparison to other RC types (e.g., Adani, 2010;de Villiers et al, 1979;Diessel & Tomasello, 2005;Friedmann, Belletti, & Rizzi, 2009;Goodluck, 2010;Guasti, Stavrakaki, & Arosio, 2012;Kas & Lukács, 2012), although more recently some scholars have noted that this effect appears to be using that, who or which. Unlike English, but similarly to German, Finnish relative pronouns are inflected for case and number.…”
