Sindarin 


noun. Haudh-en-Ndengin

mound of the slaying; haudh (“mound, grave, tomb”) + en (genitive article) + (n-)dengin (pl. of dangen “slain, slaying”) #We would rather expect it to be Hauth-e-Ndengin, so perhaps it's a dialectal variation of the name; the Etym. gives it as Haudh i Ndengin, which looks more like LR-style S with the second element Ndengin in plural.
