What words and expressions are you misusing?
Aggravate: means “to add to” an already troublesome matter or condition.
Irritate: means “to annoy.” E.g., Jeff, please do not aggravate the situation by irritating Tom—again.
And/Or: is a shortcut that damages a sentence and can lead to confusion or ambiguity. Avoid using it. Please.
Anticipate: should be replaced with the word “expect” in the sense of simple expectation. ‘Anticipate’ can sound pretentious.
As to whether: can be shorted to just the word “whether.”
Fortuitous: means “limited to what happens by chance.” Do not use it to mean fortunate or lucky.
Fixin’ to: is the Texas way of saying that you are “about to do something.” Neither Strunk nor White mentioned it
