Probably a form of -tus (adjective-forming suffix) used as a neuter substantive representing location. This may have originated from a reanalysis of ante-classical olētum (“olive yard”) from ole(a) (“olive tree”) + -tum to ol(ea) + -ē̆tum. Compare to other neuter suffixes that could form nouns representing locations, such as -ārium n, -īle n, -tōrium n (vs. masculine -ārius,-īlis, -tōrius).
-ētum n (genitive -ētī); second declension
Second-declension noun (neuter).
