Please state in which country your phrase tends to be used, what the phrase is, and what it should be.
Example:
In America, recently came across “back-petal”, instead of back-pedal. Also, still hearing “for all intensive purposes” instead of “for all intents and purposes”.
They’re, you’re
Sneak peek
In portuguese: mas/mais - people often use “mais” (plus, sum) when the correct would be mas (but)
What do people say wrong istead of “sneek peek”?
