Vocabulary diversity
4,798 distinct words and 3,795 distinct root forms across 32,469 words of text. Longer books will almost always show more, so this is worth comparing only between books of a similar length.
Vocabulary by CEFR level
Every word of the text was looked up in a CEFR-graded vocabulary list. This is the share of the running text — not of the distinct words — that sits at each level.
| Level | Share of the text | What that level means |
|---|---|---|
| A1 | 73.2% | the first few hundred words — the ones almost every course starts with |
| A2 | 9.1% | still everyday vocabulary, but past the beginner list |
| B1 | 5.6% | the level at which most people can follow a novel |
| B2 | 2.5% | comfortable general reading |
| C1 | 0.4% | precise or literary vocabulary |
| C2 | 0.3% | rare, technical or archaic |
| Off-list | 8.9% | names, places, and words no graded list covers |
How much of it you would already know
If you know the vocabulary up to a level, this is the share of the running text you would recognise on sight:
- B1 — you would recognise 87.9% of the words.
- B2 — 90.4%.
- C1 — 90.8%.
Comprehension usually becomes comfortable somewhere around 95–98% coverage, which is why the gap between those percentages matters more than it looks: how many words you need to read a book goes through the research behind that figure.

Where it gets harder
The book was split into ten equal spans and each measured on its own. Reading left to right, the scores are 39, 36, 37, 32, 36, 34, 37, 37, 27, 30. The hardest span is the first and the easiest is the ninth, so a sample from the opening is not always a fair test of the whole book.
The words it leans on

- B2 — gaze, servant, dawn, murmur, scarcely, offend, master, cast
- C1 — oblige, peasant, amid, sombre, flattery, farce, sacrifice, conviction
- C2 — hysterical, allusion, gout, allude, contrive, solitude, flit, veritable

Reading it without stopping every line
At 9.6% uncommon words, a book this size will still hand you words you do not know — that is what makes it worth reading. What slows people down is not meeting the word, it is leaving the page to look it up. ClickBook explains the word where it stands, using the sentence around it, and you keep reading.
