Common Errors in English Usage

ALL OF THE SUDDEN / ALL OF A SUDDEN

An unexpected event happens is "All of a sudden" & not "All of the sudden".

ADVANCE/ADVANCED
Advance : When we hear about something in advance, earlier than other people, you get advance notice or information.

"Advanced" means "complex, sophisticated" and doesn't necessarily
have anything to do with the revealing of secrets.

for or fore
The most common word “for,” is not a problem for most people.

& “Fore” always has to do with the front of something (it’s what you shout to warn people when you’ve sent a ball their way). …

unpleased or displeased
“Unpleased” is considered archaic; the standard modern word for your reaction to something you don’t like is “displeased.”

However “unpleasing” is still current to describe something that fails to please: “the arrangement of ‘Silent Night’ for truck air horns was unpleasing.” But “displeasing” is more common.
