Strangers or Foreigners
Common mistake
“There were many strangers at the hostel. It was great to meet so many new people.”
Strangers = people you have never met, seen or talked to. To call someone a stranger is not particularly friendly.
e.g. “Call the police! There’s a stranger walking around in our garden!”
Foreigners = people from other countries
e.g. “Nowadays, an increasing number of foreigners are coming to live in Chile”
NOTE: The word foreign means “something completely different and unknown; an outsider”. Be careful with the context in which you use the word foreigner, as it can sometimes be a little bit cold-sounding. If in doubt, use people from different countries.
Are there many foreigners in your town or city?
