From Faldage: "PRUTAH or PRUTA, (pl. PRUTOTH or PRUTOT)
Looks Hebrew to me. Sounds good by me."

Yep. In Hebrew, the -OT ending (sometimes transliterated -OTH) is the standard pluralization for feminine nouns --- and a noun whose singular form ends with -A would typically be feminine.
(e.g., the book read from in the Passover Seder-service is a haggadah, pl. haggadot)
