From an article in the Associated Press:
Spanish becoming Miami’s primary language
MIAMI – Melissa Green’s mother spoke Spanish, but she never learned – her father forbid it. Today, that’s a frequent problem in this city where the English-speaking population is outnumbered.
Given this example of a professional author’s misuse of the verb “forbid” (past tense being “forbade” or “forbad”) and professional editors’ failure to catch or correct the problem, I guess we should just be happy that *some* language is still being taught *somewhere*.
