It should be 'For All Intents And Purposes' and WOW does it fracture my ear. Are you guilty of saying or writing common phrases like that incorrectly? The answer may surprise you!

And when I write, 'the answer may surprise you', that indicates that, according to this Acrolinx article, I've discovered that I've been been wrong about something for years!

Chomping At The Bit

This Is Wrong?!?! Believe it or not, the verb is 'Champing' is an Olde English equestrian term that specifically means something a horse does with it's mouth when it is impatient.

I've grown up around several large animals and I've heard some ancient farm terms but I've NEVER picked up on Champing VS. Chomping.

For All Intensive Purposes

INTENTS AND PURPOSES! I'm sorry, I didn't mean to go all caps on you there but I loathe that incorrect phrase. I thought for a minute that this was ONLY a New Hampshire error, but sadly,  it's common throughout the entire world.

For all intents and purposes is a phrase meaning "essentially" or "in effect." It is often mistaken as for all intensive purposes because when spoken aloud these two phrases sound very similar.

Making A Commockery

I have ONLY heard this once but I thought it was so wonderfully stupid that I just had to add it to this list.

If you think about it, you can see how this phrase devolved from 'Making A Mockery' to 'Making Commockery' and then by readding the 'A', you wind up with this all time doozie.

If I ever see that one on a list of 'Idioms and Eggcorns', I may move to another solar system.
