Sorry, but it is very difficult to find on Google the difference on these terms.
Can anyone help me?
Soup, stew and broth.
Thank you for your attention!
Soup is a finished dish, usually containg stock/broth. But in the case of a chowder, for example, I wouldn't use the term stock at all
Broth and stock are not rigourously defined or used in English. They're often used interchangably. I tend to use the term stock for an unseasoned basic liquid from simmering the bones and aromatics. Broth for when that liquid is ready for use (because of seasoning/reduction) or in use in the soup.
Soup - as defined above.
Stew - thick meat-based soup.
Broth - thin, clear soup/sauce base made from meat.
Stock - thin, clear soup/sauce base made from bones.
