I've got a little list... well, quite a long list! But a few that currently set my teeth on edge are:
Burglarize.
That's not a word! The proper term is 'burgle'. It's what a burglar does - he burgles. Of course, it has to be spelt with a Z because Murica. But it's still wrong and not a word and ghastly.
Cadence
There's a trend amongst space commentators and journalists that when describing how many launches there are, it's referred to as the cadence.
"SpaceX have an incredible launch cadence" for example.
No! Cadence means either modulation or inflection, or something rhythmical. Rocket launches do not occur at regular intervals!
What they mean is the launch
rate - that's what it used to be called. I suspect someone thought it sounded clever without knowing what it means and everyone just followed along without without bothering to find out what it meant. Launch rate!
Gaming
When you operate a motor vehicle, it's called driving. When you make a cake, it's called baking. Not carring, or caking! When you play a game, it's
playing! You are a player of the game, not a gamer of the game - makes absolutely no sense!
Of course, it's obvious why it must be gaming - playing makes it sound childish and frivolous - gaming makes it sound much more serious. Back in the distant past (i.e. 10 years ago) we had "Ready Player 1", "Insert coins to play" etc. Yes, I know...multi-billion dollar industry blah blah blah, but it's still playing. That the playing of games has become a multi-billion dollar industry is a whole other can o' worms, but at least be honest about what you're doing and use the correct word - playing.
NB: Gaming properly refers to the playing of games for stakes, i.e. gambling. The authorities which oversee gaming (gambling) are called Gaming Boards or Gaming Commissions - as in
Nevada Gaming Control Board
and a final quick couple...
Head over heels
Errr... that means the right way up! If it was supposed to mean upside down, it would be heels over head...
GSW
As an abbreviation for 'Gun Shot Wound'. It's quicker to say 'Gun Shot Wound' (three syllables) than 'GSW' (five syllables) so it's not even an abbreviation!
