About 赤シート英単語帳 - 語源で覚える英単語
[Completely Free & Ad-Free] English Vocabulary App for Learning Through Etymology
Red Sheet Vocabulary is a learning app that allows you to efficiently memorize TOEIC and Eiken (English Proficiency Test) vocabulary by learning its etymology.
All features are completely free and ad-free. There are absolutely no in-app purchases.
◆ Understand "Why it has that meaning" through etymology
Instead of rote memorization, you can understand the origins of meaning from prefixes, roots, and suffixes.
Example: current
curr- (Latin currere = to run)
"Something that flows and runs" → flow, electric current, present
Once you understand this, you can easily learn related words such as currency, occur, and concur.
◆ Five Learning Modes
• Multiple Choice Quiz: Quickly check meanings
• Red Sheet: Hide Japanese translations and memorize words in a list
• Intensive Test: Focus on difficult words
• Time Attack: Measure your ability within a time limit
• Writing: Reinforce spelling by writing it out
◆ Supported Levels
【TOEIC】600 / 800 / 990
【Eiken】Grade 3 / Pre-2 / Grade 2
◆ Learning Support Features
• Text-to-Speech (Adjustable Speed)
• Visualization of Learning Data and Statistics
• Setting Daily and Weekly Word Goals
• Recording Consecutive Learning Days
• Switching between English-to-Japanese and Japanese-to-English Display
• Creating Custom Vocabulary Lists
• Adding Words to Existing Vocabulary Lists
• Notification Reminders
◆ Recommended for:
• TOEIC For those aiming for a score of 600-990
* Those planning to take the Eiken Grade 3-2 exam
* Those who struggle with rote memorization and prefer to understand words through their etymology
* Those looking for a free, ad-free app
* Those who want to study consistently every day
