✅ Check Grammar →Why grammar matters — even for native speakers
Research consistently shows that grammar errors reduce credibility. A survey by Global Lingo found that 59% of people would not use a company with obvious grammar mistakes on its website. For job applications, poorly written emails, or academic submissions, grammar errors can be the difference between success and rejection.
Even native English speakers make consistent mistakes — it's/its confusion, misplaced apostrophes, subject-verb disagreement, and run-on sentences are among the most common. A grammar checker catches these automatically so you don't have to memorize every rule.

10 most common grammar mistakes to watch for
Their / There / They're
"Their" is possessive. "There" is a place. "They're" = they are.
Its / It's
"Its" is possessive. "It's" = it is.
Your / You're
"Your" is possessive. "You're" = you are.
Effect / Affect
"Effect" is usually a noun. "Affect" is usually a verb.
Then / Than
"Then" refers to time. "Than" is used for comparisons.
Fewer / Less
Use "fewer" for countable things ("fewer apples"), "less" for uncountable ("less sugar").
Who / Whom
"Who" is a subject. "Whom" is an object. Replace with he/him: if "him" works, use "whom".
Dangling modifiers
"Walking to school, the rain started" → "Walking to school, I got caught in the rain."
Apostrophe in plurals
"Apple's" is wrong for a plural. "Apples" is correct.
Run-on sentences
Two independent clauses need a period, semicolon, or conjunction between them.
