Do I need to create an account to track my progress?

Which exams does TypoGrammar prepare me for?

Our content is mapped to IELTS (Academic & General), TOEFL iBT (2026 format), Cambridge (B1-C2), PTE Academic, and the Duolingo English Test. You'll find dedicated writing-template, reading-strategy, and vocabulary pages for each exam.

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 e.g. and i.e.?

'e.g.' comes from the Latin 'exempli gratia' meaning 'for example' — it introduces one or more examples from a larger group (I like citrus fruits, e.g., oranges and lemons). 'i.e.' comes from 'id est' meaning 'that is' — it clarifies or restates the exact meaning of something (Use the main entrance, i.e., the one facing the street).

How do I remember e.g. vs i.e.?

Think 'e.g.' = 'example given' (both start with E). Think 'i.e.' = 'in essence' or 'in other words' (both start with I). If you can replace the phrase with 'for example', use e.g. If you can replace it with 'that is to say', use i.e.

e.g. vs. i.e.: What's the Difference?

Quick Answer

e.g. = "for example" — introduces examples from a larger group

i.e. = "that is" — clarifies or restates exactly what you mean

Explanation

E.G. (for example)

Latin: exempli gratia

Introduces a non-exhaustive list of examples

"I enjoy winter sports, e.g., skiing and skating."

"Bring warm clothes, e.g., a coat or sweater."

I.E. (that is)

Latin: id est

Restates or clarifies — gives the complete, exact meaning

"Use the back entrance, i.e., the one by the parking lot."

"We meet biweekly, i.e., twice a month."

Memory trick: e.g. = "exact given examples" (a sample). i.e. = "in essence" (the full, precise meaning). Both abbreviations are typically followed by a comma in American English.

Examples

✔She speaks several languages, e.g., French and German. (examples, not the full list)

✔The deadline is the end of the quarter, i.e., March 31st. (exact clarification)

✔Bring identification, e.g., a passport or driver's license. (examples)

✔Only full-time staff, i.e., those working 40 hours a week, qualify. (precise definition)

✘I like fruits, i.e. apples and bananas.
