Origins

Rebracketing of -tum in nouns ending in -ē-tum; perhaps from veprētum (“a thicket of bramble”), from vepr-ē-s, or the early-attested olētum. The ease of attaching the vowel-initial suffix to any noun stem likely helped the suffix to supplant -tum. Compare other neuter suffixes that can form nouns representing locations, such as -ārium n, -īle n, -tōrium n (vs. masculine -ārius,-īlis, -tōrius).
