What is the English translation of the Romani gypsy word merimos?
The marime laws...
Loosely translated, that is "unclean". However, that is very loosely translated.
The marime laws run every aspect of traditional Romani life. Violating one of them gets you anywhere from punishment to expulsion from your Clan.
I am not going to go into a list of the marime laws. There are so many and they vary between Clan to Clan. Also, not all Clans follow the exact same marime laws.
Death or dying in an unclean state, basically, death or dying in a condition of marime. the frist guy is right
You can also be merimos if you're murdered and your murder is unavenged (ties into marime). The first two answerers are right also. I'm just adding that bit. It's almost impossible to explain marime to gadje so explaining merimos is just as hard.
