-crum
- From Proto-Italic *-klom by long distance dissimilation of /l..l/ > /l...r/.
- Ultimately from Proto-Indo-European *-tlom.
- Although the Proto-Indo-European suffix had a variant with *r (*-trom, the ancestor of Latin -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.
- Compare -āris, a dissimilated allomorph of -ālis.
- (Classical Latin) IPA(key): [krũː]
- (modern Italianate Ecclesiastical) IPA(key): [krum]
-crum n (genitive -crī); second declension
- alternative form of -culum (used only when /l/ occurs earlier in the word)
Second-declension noun (neuter).
