- Casualty– a person who is killed, or injured, in a war or disaster.
- Momentarily– For a moment or an instant. (Not IN a moment.)
- Daily Savings Time– The official term is “daylight saving time,” not “savings time.”
- LCD Display– “LCD” stands for “liquid crystal display,” so it is redundant to write “LCD display.” Use “LCD screen” instead.
- Please RSVP– R.S.V.P. stands for the French phrase Répondez s’il vous plaît (“reply, please”), so it doesn’t need an added “please.” However, since few people seem to know its literal meaning, it’s probably best to simply use “Please reply.”
- UFO– “UFO” stands for “Unidentified Flying Object,”so if you’re sure that silvery disk is an alien spacecraft, there’s no point in calling it a “UFO.”
- You can’t have your cake and eat it too– The original version of this saying is “You can’t eat your cake and have it too,” meaning that if you eat your cake you won’t have it any more. (It’s confusing because we use the expression “have some cake” to mean “eat some cake.”)
