On a similar note, I've heard that the words for animals, like cow or pig, tend to be Germanic while the words for their meat, like beef or pork tend to be Latin.
Beef <- Boeuf
Pork <- Porc
Poultry <- Poulet
Salmon <- Saumon
Venison <- Venaison
Mutton <- Mouton
The latin words are in some cases the root of the French but it's not as clear or consistent.
