Examples:
"I live in England." (This means I reside there.)
"I am from the USA." (This means I was born there, and/or reside there, and is likely where a significant time of my life was spent, particularly the early years.)
**"I am from Norway."/ "My family is from Norway." (This means the origins of the family come from somewhere else.)
**Sometimes, there are people who loosely use the word "from" when it comes to where their family migrated from prior to their birth. You may have seen Ancestry.com commercials starring Kelly Ripa. Ms Ripa makes the claim, "I'm from the big toe of that sexy Italian boot!" Ms Ripa has Italian ancestry, but make no mistake about it -- she was born and raised in New Jersey, USA.
This is often something Americans and Canadians do when they bypass their actual origins and tell people (for example), "My family's from Scotland." The truth is, they are *not* from Scotland (and chances are, neither are their parents) but their ancestry means enough for them to make this claim.
