How is TypoGrammar different from Grammarly or Duolingo?

Grammarly fixes your sentences but rarely teaches the underlying rule. Duolingo gamifies short drills. TypoGrammar focuses on understanding - every lesson explains why a structure works, with examples, mistakes to avoid, and a quick quiz to lock it in.

How long does it take to see results with TypoGrammar?

Most learners report a noticeable improvement in writing accuracy within 2-3 weeks of daily 15-minute sessions. The verb-tenses quiz gives you a personal weak-area breakdown, so you can target exactly the tenses you keep getting wrong.

Can I use TypoGrammar on my phone?

Yes - the entire site is mobile-first. Lessons, quizzes, and the grammar checker all work in any modern mobile browser. There is no app to install.

What is the difference between there, their, and they're?

'There' refers to a place (over there) or existence (There is a problem). 'Their' is a possessive pronoun meaning 'belonging to them' (their house, their ideas). 'They're' is a contraction of 'they are' (They're coming soon).

How do I remember there, their, and they're?

Test 1: Can you replace it with 'they are'? → use they're. Test 2: Does it show ownership? → use their. Test 3: Does it refer to a place or existence? → use there. The word 'here' is inside 'there' — both refer to place.

There vs. Their vs. They're

Quick Answer

there = place or existence (Put it over there. There is a way.)

their = possessive pronoun (their house, their ideas)

they're = contraction of "they are" (They're coming.)

Explanation

THERE

1. Place (≠ here)

2. Existence (there is/are)

"Put it over there."

"There is a problem."

Tip: "here" is inside "there"

THEIR

Possessive — belonging to them

"Their house is big."

"I like their music."

Like: my, your, his, her, our

THEY'RE

Contraction: they are

"They're coming soon."

"They're my friends."

Test: replace with "they are"

Memory trick: The word here is hidden inside there — both deal with place. Their contains heir — someone who inherits (owns) things. They're has an apostrophe → contraction of "they are".

Examples

✔I left my keys over there. (place)

✔Their flight was delayed. (possessive)

✔They're planning a trip to Japan. (they are)

✔There are many ways to solve this problem.

✘I love there new apartment.

✘Their going to be late.

Common Mistakes

Incorrect: Have you seen there new car?

Correct: Have you seen their new car? (possessive — belonging to them)

Incorrect: They're house is beautiful.

Correct: Their house is beautiful. ("they are house" ✘ → use their)
