The word is "definitely"

That's d-e-f-i-n-I-t-e-l-y. Not definately. Not defiantly. The first one is not a word; the second is how I act when people try to tell me it's spelled "definately."

While I'm at it...

• MOOT point.
• A Lot. Not Alot. NOT Alot.
• Voila. Not waa-lah. Not viola - which is an instrument, not an exclamation. At least not the last time I checked.
• Sincerely has a second "e." Sincerly is not a word, unless I've missed out on the sincer-ing trend. I didn't get the memo...
• Supposedly. Supposably is, as it turns out, a real word (gag). But it's almost never used correctly, so stop using it until you can use it in its correct context.
• Pregnant. Pregnate is not a word. It's stupid.
• Y'all. Y-apostrophe-all. Not ya'll. Unless you can tell me what "ya" is short for.
• Your - of or relating to you. NOT short for "you are."
• You're - "You." "Are." For cripe's sake, stop saying "Your welcome." My welcome...what? Mat?
• Too - Also. Or to an excessive degree. "I'm too tired." "I like that, too." If you say "I like that to," you're missing a word. You like it to what?
• It's means "it is." "It's the moose's hairpin."
• Its means "of or relating to it." Clarified: "The moose loves its hairpins."
• You could NOT care less. Saying you could care less is meaningless.

Most of all, though, definitely remember "definitely." My new quest in life is to rid the world of all definatelys and defiantlys. Mercy. It hurt just to type those out.
