How it is calculated
Words are normalised (lower case, no harakat or tatweel). Unique words = number of distinct words. Lexical diversity % = unique words ÷ total words × 100.
Example
Result: Unique words: 19; Total words: 24; Words used once: 17.

Limits and caveats
- Different forms such as «كتاب», «الكتاب» and «كتب» count as different words.
- Diversity naturally falls as text gets longer, so compare texts of similar length.
Questions about this tool
What does lexical diversity mean?
It is the share of distinct words among all words. A higher value means less repetition and a wider vocabulary.
In what form does each word appear in the list?
Each word appears as it was first written in the text, in order of first appearance.
Are "Hat" and "hat" two words?
No. Comparison ignores letter case, so they count as one word.
