The reanalysis of /ɡ/ as a verb class marker: An exaptation case within the Catalan 2nd conjugation

In Old Catalan, some verbs like beure ‘to drink’ display a velar consonant in the forms that come from Latin perfectum, such as 3sg.prt *ˈbibwit > bec [ˈbek] ‘s/he drank’. This velar was initially a perfect marker. However, the consonant spread analogically from perfective to imperfective forms through an exaptation process. In the present paper, we compare two different verb classes, and prove that the existence of syncretism between the first and third persons of the present indicative (1sg.prs.ind beu [ˈbew] ‘I drink’ vs. 3sg.prs.ind beu [ˈbew] ‘s/he drinks’) is a factor that accelerates the analogical process of velarization.
