I rarely misspell things . . . mistype, on the other hand . . . Oi.
That’s “weird,” unless you were joking when you spelled it “ie” (in which case, my bad).

I was the only child in the fourth grade class to miss this one on a spelling test and the humiliation has made me unable to do le/el words at all

HELP
I was taught as a child to remember that there’s “a rat” in separate. Helps.
Me? I spell cancelled with two l’s and spellcheckers have fits with it, though the dictionary says it’s ok…
This is (by a wide margin) the most common problem that I encounter. And it’s strange that it should be, because it’s one of the easiest things to remember:
it’s (with apostrophe) = it is (always, without fail)
So, if you’re trying to say “it is”, use “it’s”; otherwise, it’s “its”.
“It’s” can also mean “it has” as in “It’s been a long time.”
The words I misspell is too long to list. I hate spelling.

I always spell originally wrong. I tend to spell it origionally. Not entirely sure why?
Nods knowingly My teen friends drive me nuts because they type that… that… cyber-teen-speak way, and I can’t help but notice every single one of their “mistakes”. I just know it’s wrong, whether it’s me or them, and it grates on my nerves… :mad:
Mayberrydan, I do that too, especially when I’m writing - maybe because that’s almost how I pronounce it? (I tend to remember how to spell by pronouncing the words mentally)
I also spell Buddha “Bhudda” for some reason… again, stupid mental pronounciations.
“Weird” trips me up a lot too… it just looks “wierd” both ways. Worse yet, when I’m typing in a hurry and turn it into “wired”, which usually makes absolutely no sense in context.
I feel so much better now, knowing I’m not the only one that screws up “weird”. And I also tend to use "strange’ instead!
I misspelled “tomorrow” until earlier this year. I always spelled it “tomarrow” and never even realized it was wrong.
I also occasionally mistype desperate and separate–I had to fix separate just now.
“wheather, weather, whether?”
always mistype “teh, the”
I used to have a problem with together until I realised its just “to get her” joined together 
I hardly dare open my mouth. My English is bad.
Thanks for the “its” vs. “it’s”
Also; can anyone help me with “off” vs. “of”?
Thanks
*To pronounce, I have difficulties with the word “everything”. I haven’t the slightest why. *
Great responses! Here are a couple more of my word enemies:
Rhyme: What is the deal with the H - Y - M baloney?
Oh yeah - Baloney/Bologna
Familiar and Similar: I cannot remember which has the “lar” and which has the “liar”
Anyway, that’s enough honisty for now…
I KNOW there’s a rat in separate, but I still think that separate and seperate are two different words with different pronunciations and should therefore be spelled differently.
*Those are two separate things.
and
*I need to seperate those two children.
See? To me, that makes sense, and it took me forever to get it into my head that I’m wrong (and deep in my heart I still think I’m right despite all evidence to the contrary.)
I rarely have trouble with other homophones or homonyms, so go figure.
As for “off” and “of” – off is pronounced OFF, as in get OFF the sofa. Of is pronounced OV as in she’s one OF them. Does that help, kase?
receive.
or, possibly, recieve.
I forget. 
Hey! Yes! Thanks LifeOnWry
I’m an excellent speller and grammarian. Always have been.
And yet, whenever I write the word “embarrass,” I have to pause and think: one R or two?
For similar reasons, I also have to think about “sheriff” and “graffiti.”
Other than those, I’m golden.
It’s comforting to see quite a few people are in the same boat as me - generally pretty good at spelling, but with just one or two strange and inexplicable blank spots.
Mine include words like ‘independent’ which I tend to end with ‘-ant’ instead of ‘-ent’. I have to catch myself and correct the error each time.
I was having trouble with “guarantee” until Sapphire Bullet set me straight…now when spelling it I repeat in my head “I guarantee there are no e’s until the end of that word.”
Maintanance…maintanence? Maintenence? Maintenance? One of those is right. I’m damned if I know which one.
Because comes out Becasue for me all the time, too. I know how to spell it; that one’s purely typographical.
There are, of course, the quickly mistyped “teh” and “og” words…
And “occuring” always has two r’s when I type it. Except here. Occurring. And half the time I put two c’s AND two v’s in “vacuum” (so…“vaccuum”) because I never used to remember which letter was doubled so I always doubled both. I suppose I figured you can’t have too much of a good thing. 
aparrently. I never can remember if it’s the p or the r (or both) that gets doubled.
I always misspell “excersise” and “suprise”.
What really annoys me about those words is that I misspell them in a way that spellcheckers generally cannot find, and it takes a few tries before I can get the correct spelling to pop up.
