Typos, improper grammar, spelling errors -- they're everywhere you look. Whether in a hasty post on social media or a mangled listing on a menu, typos bug Americans the most, according to Dictionary.com. The site released its "Grammar Gripes 2015" report detailing Americans' biggest pet peeves and how they feel about their own spelling.

Harris Poll surveyed 2,052 Americans over the age of 18 about spelling and grammar. Eighty percent said they were good spellers, with females age 35-44 being the most confident (87 percent) in their abilities. The Northeast (83 percent) was the region most confident in its spelling by a narrow margin. The South (81 percent) was in second place, while the Midwest and West were tied at 78 percent each.

The percentages don't necessarily reflect the truth about spelling since they are based on self-reported responses. Another section of the survey found 71 percent of those polled spotted spelling errors in written exchanges.

"We were glad to see that Americans are paying close attention to grammar and spelling, though some of the findings did come as a bit of a surprise,” Liz McMillan, chief executive officer of Dictionary.com, said in a statement.

In the battle of the sexes, females win. Women said they were good spellers, spotted mistakes and were annoyed by grammar mistakes, according to Dictionary.com. Among females surveyed, 75 percent said they often find spelling errors in written correspondence, compared with 66 percent of males. Asked if improper grammar was their biggest annoyance, 62 percent of females responded "strongly/somewhat agree" compared with 55 percent of males.

Millennials -- adults 18-34 -- were the most annoyed by grammar mistakes. The champions of emoji and acronyms said finding a spelling mistake on social media bothered them (74 percent). They were irritated by menu or store typos (63 percent) and considered improper grammar to be their biggest pet peeve (65 percent). Not content to let poor grammar go unchecked, 63 percent of adults 18-34 said they correct family or friends when they misspeak, whereas 47 percent of adults 35-44 said they made those corrections.

Misspellings of February (as Febuary) annoyed participants the most, with 38 percent of those polled saying it bothered them. Definitely (definately), receive (recieve), grateful (greatful) and weird (wierd) rounded out the top five.

For commonly confused terms, it's no surprise their vs. they're vs. there won, with 46 percent of participants saying the incorrect usage annoyed them the most. Your vs. you're, to vs. too vs. two, me vs. I and accept vs. except were among the confused words that most irked Americans.

So disinterested in something that you could care less? Well, you're saying it wrong. The confusion between "could care less" and "couldn't care less" distressed Americans the most (49 percent). Other annoyances included using irregardless instead of regardless, anyways instead of anyway, snuck instead of sneaked and upmost instead of utmost.
