Spelling & Grammar Trainer
Practice spelling, false friends, tricky words, prepositions, and articles through short sessions with immediate feedback.
This tool helps you practice words such as running, environment, actually, or necessary, plus short structures with prepositions and articles.
Practice runs in your browser and saves only local progress with IndexedDB. It does not require an account, does not send answers to servers, and lets you reset progress from the tool settings.
Use cases
- Memorize spelling for frequent words, false friends, and common mistakes.
- Practice active recall by typing the word, not only recognizing it.
- Practice prepositions and articles by filling blanks.
How to use it
- 1 Choose a 5, 10, or 15 exercise session from Settings.
- 2 Complete exercises in four modes: build the word, listen and type, choose the correct option, or fill blanks.
- 3 Review the final summary to see correct answers, strengthened words, and the suggested focus for your next practice.
Technical details
- The item list is bundled as static site data, and selection combines new content with directed review.
- IndexedDB stores per-item progress, general stats, and basic preferences only on the device.
- Audio feedback uses local files when available and browser SpeechSynthesis to pronounce correct words.
FAQ
Is my progress uploaded to a server?
No. Progress is saved locally in your browser with IndexedDB, and you can delete it from Settings.
Why are there four modes?
Because recognizing a word is not the same as spelling it, and using a preposition in context is not the same as memorizing it alone. The tool mixes building, visual discrimination, active typing, and blanks.
