GOsh! "Then" and "than" drives me nuts 'cuz even so-called teachers don't know it.
Worst of it all, they confuse students like me who know the right way and were thought the right way from childhood.
I always see them say "rather then" instead of "rather than". It drives me nuts . . . are people that dumb? Maybe if they start to read their hymnals again, then they'll learn good English.
"Affect" vs. "effect" is the same story. I always used it perfectly fine until I started to see the so-called press mix the two up. My teacher's little lecture helped reinstate my confidence.
See folks, here are good examples of "affect" vs. "effect":
Queen Elizabeth is deeply affected by her sister's death.
The effect of toxic waste in our community is present in birth deformities.
What effects do you expect it will have upon your pursuit of politics?
How affected are you with Princess Margaret's death?
Do you think it would affect you if AT was down today?
Now, I don't trust any spelling others put if it is different from mine.
Another great example is "existence" versus "existance". For God's sake folks, it is an "e", not an "a".
Even people who claim to be intellects cannot spell such simple words. It drives me nuts! What is becoming of our so-called educational system. *Scared my kids will have to adapt to a new spelling method 'cuz a bunch of partially illiterate members of society are winning the battle of the English language! :|
