Okay, I just needed to get this off my chest, but there are some grammatical errors that grind my gears:

• On accident — by accident
• Chalk full of — chock full of 
• Bear necessities — bare necessities (I know it’s confusing because the Disney song is sung by a bear but stop)
• Bare with me — bear with me
• Peaked her interest — piqued her interest
• For all intensive purposes — for all intents and purposes
• Reek the benefits — reap the benefits (What would “reek” the benefits even mean???)
• Sneak peak — sneak peek
• Doesn’t phase me — doesn’t faze me
• Should of – should’ve/should have (applies to the entire “-ould” coven)
• Wheelbarrel — wheelbarrow (I know, this one blew my mind but ’tis true; trust your spellchecker here)
• Pour over a book — pore over a book

These are the ones I could think of for now. I know that sometimes meanings change with how the language is used, but sometimes that’s ridiculous, isn’t it? (See: “literally”) These are little things that are common mistakes, many that are very easy to make and maybe difficult or even unreasonable to change. But oh well!

Are there any grammatical mistakes that drive you a little crazy?
