sith-nom
Preserved but no longer current.
A month. This is because the slang was made from months, not month. Perhaps because the latter was not easy; perhaps because terms of imprisonment run longer than a month, and are often enumerated in the "kacab genals." However it may be, "months" in this mode of speaking has a double plural as it stands now.
Era: ca. 1874 (Victorian)
