"horse" + "course" + "car" + "hurry"

4 words: all have to do with running, but not "curry" (in the sense we know most):

horse

• Proto-West Germanic *hors or *hross
  • Proto-Germanic *hrussą ("horse")
    • PIE *ḱr̥sós ("vehicle")
    • PIE *ḱers- ("to run")

course

• Old French cours ("course")
  • Latin cursus ("course")
  • Latin currō ("to run")
    • PIE *ḱers- ("to run")

car

• Old French carre ("car")
  • Latin carrus ("wagon")
    • Proto-Celtic *karros ("wagon")
      • PIE *ḱr̥sós ("vehicle")
      • PIE *ḱers- ("to run")

hurry

• Proto-Germanic *hurzaną ("to rush")
  • PIE *ḱers- ("to run")

curry

(in the sense of a sharp, brothy dish from India)

• Tamil கறி (kaṟi)
  • Middle English cury ("to cook", "something which is cooked")
    • Middle French cuyre ("to cook")
      • Latin coquere ("to cook")
        • Proto-Italic *kʷekʷō ("to cook")
          • PIE pékʷeti ("to cook")

oddly enough:

• English does have another sense of "curry"
  • it means "hurry" but not often said
  • from the same background as "hurry" from *hurzaną
    • likely through "rhyme-twinning"
      • e.g. "pitter-patter" or "flip-flop"
