In spite of what Monty Python would have you believe, it is NOT "fetchez la vache." ;-)
You would say apporte la vache to a friend, or apportez la vache in a more formal context.
Answer:
Animals "talk" differently around the word (See Link) and some vary widely for different locations. For cows most of the sounds are similar to the English "Moo" but may be spelt differently:
La vache (fem.) is the french word for the cow
A herd of cows is "un troupeau de vaches" in French.
a cow is called une vache (fem.) in French.
chercher la vache
Obtenir la vache
Cow manure is "le fumier" (masc.) in French.
The little cow is "la petite vache" in French. The calf is "le veau".
vache sacrée
the sound of the mooing cow is written 'meuh' in French.
French kids use the expression 'grosse vache' for the English 'big fat cow'.
A cow is called 'une vache' in French.
I'm pretty sure it's "vache heureuse." It is feminine.
cesser de péter, vache paresseuse
"Vas-y" "Lance toi"
moo in french is "mieu" although cows do not ACTUALLY say moo. If you listen to a cow they actually say ner.
The French word for cow is 'Vache', and would be used to refer to the female.
Spanish: vaca French: vache German: Kuh Italian: mucca
