What year was the typewriter invented?
In 1867, Christopher Latham Sholes invented the QWERTY keyboard layout to prevent key jams in mechanical typewriters. Mechanical typewriters utilized metal bars with character shapes that swung upwards to hit ink ribbons. If a typist typed consecutive characters located close to each other too quickly, the bars clashed and jammed. QWERTY separated frequent letter combinations across the keyboard, decreasing mechanical jamming and shaping modern computer keyboards forever.

What Is the English Grammar Test?
Our free English grammar test is an interactive quiz where you identify grammatical, punctuation, and syntax errors hidden within sentences. Each sentence is displayed word-by-word and you click on the word or phrase containing the error. This active error-spotting format trains your eye to recognize common grammar mistakes — making it far more effective than passively reading grammar rules.
How to Take the Grammar Test
Click 'Start Test' to begin. Each round presents a sentence with one deliberate grammatical error. Read the sentence carefully and click on the word or phrase you believe contains the error. After each answer, you receive immediate feedback explaining whether you were correct and why. The test tracks your score across 5 sentences and shows your final accuracy at the end.
What Grammar Topics Are Covered?
Our grammar test covers the most commonly tested and frequently confused areas of English grammar, including:
| Grammar Category | Examples of Common Errors |
|---|---|
| Subject-Verb Agreement | "The team are ready" vs "The team is ready" |
| Pronoun Reference | "Everyone should bring their book" vs "his or her book" |
| Apostrophe Usage | "it's" vs "its" — possessive vs contraction |
| Comma Splices | Joining two independent clauses with only a comma |
| Dangling Modifiers | "Running fast, the bus was missed" — unclear subject |
| Tense Consistency | Shifting between past and present tense incorrectly |
| Capitalization | Incorrectly capitalizing common nouns or seasons |
| Punctuation Placement | Misplaced commas, colons, and semicolons |
Why Grammar Matters for Professional Writing
Grammar errors undermine your credibility. A study by Grammarly found that LinkedIn users with grammar errors in their profiles received significantly fewer job inquiries than those with error-free content. In business communication, poorly worded emails and reports can cause costly misunderstandings. Solid grammar is foundational to effective writing — whether you are crafting a job application, business proposal, marketing copy, or academic assignment.
Tips to Improve Your English Grammar
The most effective path to better grammar is through consistent reading of high-quality prose — newspapers like The Guardian, The New York Times, or books by skilled authors. Actively look up any grammar rules you are uncertain about rather than guessing. Write regularly and use tools like Grammarly to flag errors, but always read the explanations so you understand the rule rather than just accepting the correction.

Subject-verb agreement errors, incorrect apostrophe use (its vs it's), and comma splices are among the most common grammar mistakes in English writing at all levels.
Can this test help me prepare for the IELTS or TOEFL?
Yes. Recognizing grammatical errors is a core skill tested in the IELTS Writing and TOEFL Writing sections. Regular practice with our grammar quiz improves your error identification and correction abilities, which directly supports your exam performance.
What is the difference between grammar and punctuation?
Grammar refers to the structural rules of a language — how words, phrases, and clauses are combined. Punctuation refers to marks like commas, periods, and apostrophes that organize and clarify written text. Both fall under the broader umbrella of 'writing mechanics,' and both are tested in our grammar quiz.
How can I practice English grammar effectively?
Combine passive exposure (reading well-written content daily) with active practice (writing regularly and reviewing errors). Grammar quizzes like ours accelerate learning by forcing active recognition of specific error patterns, which is more effective than passive rule memorization.
