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”.
Despite the down votes I suspect most linguists would agree with you as they generally disagree with prescriptivism. Language is fluid and ever changing. Many of the phrases we have that have survived hundreds of years have altered and changed many times over to fit the era. Many linguists believe language always alters towards efficiency over time. Staunchly insisting people continue to use things in the original way is just classism disguised as education. Ironically, yours was the more educated comment in here, imo.
