Understanding English Text Difficulty
Reading at the right level is crucial for language acquisition. This tool helps you evaluate English texts by breaking down every word into CEFR proficiency levels.
The analyzer checks each word against a curated frequency-ranked English dictionary. Common function words (the, is, and) are A1, while words like "ephemeral" or "acquiescence" fall into C1-C2 territory.
Research shows that understanding 90-95% of words in a text creates the ideal conditions for incidental vocabulary acquisition — learning new words naturally through context.
