Frequency and morphological irregularity are independent variables. Evidence from a corpus study of Spanish verbs
AbstractWe present the results of the first corpus analysis of Spanish verbs where the correlation between morphological irregularity and frequency was considered. In English, irregular verbs are more frequent than regular ones (Ullman, 1999 and Michel et al., 2011). We tested whether this frequency-irregularity relation observed in English would also hold in a more complex morphological system like Spanish. Results show that frequency and morphological irregularity do not correlate in Spanish. This pattern of results represents a challenge for the Dual-Mechanism model of morphology (Pinker and Prince 1988; Pinker and Ullman 2002), where all irregulars are argued to be stored whole in memory and are predicted to be more frequent than regulars.
