The Early Acquisition of Morphology in Agglutinating Languages: The Case of Hungarian

“…A large body of work investigated how toddlers and young children produce morphologically complex forms, starting with Berko's (1958) famous wug-test, showing for the first time experimentally, young children's productive and generalized use of morphological rules. Similar investigations in Hungarian (Gósy, 1984;MacWhinney, 1975MacWhinney, , 1976Pléh et al, 2002;Réger, 1979) have also shown that pre-schoolers and schoolaged children productively apply morphological rules, with the U-shaped developmental trajectory also found in other languages, whereby in the early stages of production, irregular forms are produced correctly from rote memory, then rules are overgeneralized and irregular forms get regularized as a result, finally the irregulars emerge again correctly. In accordance with the dual-process hypothesis, different stem categories show different developmental timing.…”

“…How do they learn allomorphic stems? Do they show similar learning patterns as those observed in preschoolers in production (MacWhinney et al, 1985;Pléh et al, 2002)? Future investigations will need to address these and other relevant questions.…”

“…In accordance with the dual-process hypothesis, different stem categories show different developmental timing. Regular stem classes are produced accurately already by age 3, while some of the irregular ones involving strong allomorphy are not adult-like before 7 years (MacWhinney, 1975(MacWhinney, , 1976Pléh et al, 2002). The use of multiple suffixes, e.g.…”

“…a plural and an accusative case marker (e.g. ház-ak-at house.pl.acc 'houses.acc'), has been found to develop more slowly than the use of a single suffix (Pléh et al, 1997(Pléh et al, , 2002. Interestingly, Hungarian children with language impairment also follow a very similar developmental pattern, and perform less well than language level matched typical infants only in the case of multiple suffixes, and even in this case, produce grammatical, but simpler forms by omitting of one of the suffixes rather than totally ungrammatical forms (Lukács, 2010).…”

“…Experimental studies also explored in great detail the knowledge underlying preschool children 's production. and comprehension abilities (MacWhinney et al, 1985), and not surprisingly, how children learn and represent morphologically complex words was one of the central questions (Lukács et al, 2001(Lukács et al, , 2004Pléh et al, 1997Pléh et al, , 2002Pléh et al, , 2003.…”
