:award:
somebody finally got it
Forgive me if I sound like a total idiot here but, is the statement predicate logic or something? I still dont get it. 
The sentence SAYS it has THREE errors - which it doesn’t so the sentence itself is incorrect and therefore one of the errors
(paradox)
Hehehe…you guys completely entertained me with this one! I love the ‘This sentence has no errors’ exercise…will definitely try it on people…you intimidate me with your perfect grammar and punctuation though…need to find people more lax in their writing in another thread now
I teach classes on a regular basis (classes of software developers - geeks?) and I use this puzzle to help ‘open the mind’ a bit.
The way I present it (as a point of reference if you want to share it with others) is like this:
“There is three errers in this sentence.” Find them
When I reveal the answer it is in this way:
The misspelling of “errors” is a spelling error
The use of “is” rather than “are” is a grammar error
The fact that these are the only mistakes is a contextual error
My other favorite is “The Three Light Bulb” puzzle
Oh! Now I get it! That is pretty clever… I haven’t paid much attention to literary devices since I left college; paradox, onomatopoeia, hyperbole I have such a faint memory.
using online tools to grammars and spelling is not bad at all. But sometimes, these machines aren’t always reliable. It’s much better if you know the grammar rules by heart and use a dictionary to check your spelling. Well, of course reading can help you to widen your vocabulary.
As long as we’re critiquing, this sentence doesn’t make sense! The word “using” should be capilized, the word “grammars” should be singular as there is no such word as “grammars”, the word “check” should’ve been inserted after the word “to” and there possibly should have been the word “mistakes” after the word “spelling”, also the sentence should end with a exclamation mark. So it should read:
Using online tools to check grammar and spelling mistakes is not bad at all!
Anyway, I am a firm believer in correct grammar and spelling and this thread is quite amusing; enjoyed Rudy’s exercise immensely!
Did you mean “capitalize” ? 
This is where proof-reading comes in. What does “capilized” mean anyway? 
forced through extremely narrow blood vessels
It’s not a word, is it? Webster and Google both don’t think so. “Capillary” is, but I don’t think “capilized” is!
gotcha again, dude
Good one! I was starting to think maybe it was one of those medical terms , as I knew it wasn’t a real word.
