Seeing this use of invoke on Yahoo! Style evokes memories of past mistakes made by Yahoo! writers:
If you mean “to call for support or assistance,” use invoke. If you mean (as this writer did) “to call to mind,” use evoke (as this writer didn’t).
The editors for Yahoo! News‘ “The Lookout” should invoke a dictionary in the hopes that it evokes the correct word in this headline:
The verb invoke means “to call upon something, especially aid, assistance, or a higher power.” It can also mean”to cite for justification or to resort to.” The correct word for this headline is evoke, which means “to call to mind or call up a memory from the past.”
