Coverage = the share of words in the text you already know. The research gives two lines: 98% before independent fluent reading is realistic, 95% for the instructional level that needs support (Hu & Nation, 2000). Proper nouns are not counted as unknown — recognising that it is a name is enough; this book has 472 of them.

Read a bit of it first

The opening of Lady Chatterley's lover, word for word. Tap any word you don't know and its meaning here appears beside it — no sign-up, tap as often as you like.

Connie and Clifford came home to Wragby in the autumn of 1920. Miss Chatterley, still disgusted at her brother's defection, had departed and was living in a little flat in London.

Wragby was a long low old house in brown stone, begun about the middle of the eighteenth century, and added on to, till it was a warren of a place without much distinction. It stood on an eminence in a rather fine old park of oak trees, but alas, one could see in the near distance the chimney of Tevershall pit, with its clouds of steam and smoke, and on the damp, hazy distance of the hill the raw straggle of Tevershall village, a village which began almost at the park gates, and trailed in utter hopeless ugliness for a long and gruesome mile: houses, rows of wretched, small, begrimed, brick houses, with black slate roofs for lids, sharp angles and wilful, blank dreariness.

Computed by Readii from the public-domain text (updated 2026-10-21), not estimated by hand. The Readii reading level is our own scale, anchored on unknown-word density; it is not the same system as Lexile or AR and does not convert directly. Unknown words are measured against the CET-4 ∪ Gaokao lists, so this is difficulty for a Chinese-speaking learner, not a native-child reading level.
