ETYMOLOGY
from Greek ὀψιγαµία (opsigamia, marriage late in life),
from ὀψίγαµ-ος (late-married),
formed on ὀψέ, ὀψι– (late) + γάµος (marriage)
EXAMPLE
“…Nor is there any danger of Donald’s being flogged for opsigamy by the Highland nymphs, as the Spartans were of old. Marriage is here as much matter of course as eating and drinking; and as the sexes are more truly balanced than in Arabia, no pining damsel need sing, “Oh what will I do for a man…”
