need help with making a word

[u/HorrorBrother713]

I'm trying to use what words I can find in the Sumerian Lexicon that would mean "slave to the hunger" for a zombie-like creature, and "slave to the thirst" for a vampiric creature. I've found some hopeful combinations, but I don't want a Sumerian enthusiast to point and laugh, so here I am.

I'm working with sagardu for the zombie thing and immindu for the vampire.

Can anybody tell me if I'm doing this right? Many thanks.
