-crum

crum Latin Etymology la :inh itc-pro:*-klom From la itc-pro *-klom by long distance dissimilation of /l..l/ > /l...r/. Ultimately from la ine-pro *-tlom. Although the Proto-Indo-European suffix had a variant with *r (ine-pro *-trom, the ancestor of Latin la -trum), the /k/ in -crum indicates that it comes from *tlom, since Proto-Indo-European *t was regularly changed to *k in Italic before *l, but not before *r. Based on the form of Umbrian ehvelklu 'decretum', the dissimilation to /r/ that created the form -crum postdates Proto-Italic.The Proto-Indo-European Instrument Noun Suffix *-tlom and its Variants, Birgit Anette Olsen, 1988. §6.5 page 31 Compare la -āris, a dissimilated allomorph of la -ālis.
