What is difference between Ketchup and a Sauce?

i think both are same

simple, kethup is made from tomatoes and sauce can be made from anything,like mint sauce,mustard sauce--whatever.got it.

nothing coz ur question is 'Whai is the difference b/w "tomato sauce and tomato sauce" ' lol...

they are two words said in two differnt countries !

I do not think any significant difference between the two. The ketchup will have garlic and onions, whereas the sauce will not have onion and garlic.
