This is where a word list stops being a shortcut and becomes the only instrument that works. The words in these two books are common enough that you need them constantly and rare enough that you will not meet the same one twice in a month by accident, and closing that particular gap is the one thing a list can do that reading cannot.
Everything above and below this band has an alternative. Below it, ordinary input supplies the words on its own. Above it, the words are rare enough that most learners do not need them without a specific reason. Here there is no alternative, and that is why the set is worth owning at all.
Sixteen from this band, with a sentence for each
Chosen here rather than copied from any list, and each one set in a scene so it has something to hang on.
- appreciate, to be grateful for, or to understand the value of. Nadia appreciated the lift home more than the present.
- arrange, to organise in advance. He arranged the tasting for the Thursday before the market.
- complain, to say you are unhappy about something. Nobody complained about the noise until the third week.
- deserve, to have earned something. After four months on the roof, the crew deserved the long weekend.
- encourage, to give somebody confidence to do something. Her tutor encouraged her to sit the exam a year early.
- hesitate, to pause before acting because you are unsure. She hesitated at the door and then knocked.
- maintain, to keep in good condition, or to keep asserting. The bakery maintained the same recipe for thirty years.
- obvious, easy to see or understand. The fault was obvious once the panel came off.
- persuade, to make somebody agree by giving reasons. It took two evenings to persuade the committee.
- reduce, to make smaller. They reduced the delivery window from a week to two days.
- reveal, to make known something that was hidden. The survey revealed a crack under the plaster.
- struggle, to have difficulty doing something. He struggled with the second exam and passed the first easily.
- urgent, needing attention immediately. The message was marked urgent and had waited two days.
- familiar, known from before. The street was familiar and she could not say why.
- delay, to make something happen later, or the wait itself. The delay was ninety minutes and nobody was told.
- expand, to become larger. The workshop expanded into the yard next door in 2026.
Why it slows down, and why that is the method working
The first two books went quickly because they were mostly confirmation. This one moves at the real rate of learning a word you did not have, which is slower by a large factor, and the change is abrupt enough to feel like something breaking.
That is the stall, and it is a stall about pace rather than about difficulty. A learner who took six weeks over the first two books plans six weeks for these and is a third of the way through at the end of it, concludes that either the books or they have stopped working, and stops. Nothing has gone wrong. The early speed was a measurement of what you already knew, and it was never a rate that could continue.
The practical consequence is to plan this band in months and to judge it by whether the words are arriving in your own sentences rather than by how many units are behind you.
The discount here is real and it is not evenly given out
Words for opinion, cause and abstraction came into English from Latin and French, so they arrive in this band in a block. If your first language is Spanish, French, Italian or Portuguese, a large share of these words is recognisable on sight and the band costs you a fraction of what the books assume. If it is Persian, Turkish, Arabic, Chinese, Japanese or Korean, no such discount exists and every word is a new word.
Two learners can therefore work the same book at completely different speeds without either of them doing anything wrong, and knowing which one you are is worth more than any study technique. It changes how many months to plan and it changes what a slow week means.
The discount has a price attached for the people who get it. Words that look identical across the two languages have often drifted apart, so eventually, actually and sensible mean something other than what a Romance speaker expects, and recognising a word on sight is exactly what stops you from checking.
Where these words live in quantity
Project Gutenberg is free, needs no account, and holds tens of thousands of complete books, which matters here because this band is met properly only in long-form prose. A novel gives you these words repeatedly across three hundred pages, which is the density that no course and no article supplies.
Its limitation is specific and worth knowing before you rely on it: almost everything in it is out of copyright, so the English is largely from before about the nineteen thirties. For grammar and for the common core that hardly matters. For this band it does, because a slice of the abstract vocabulary in an older novel is now formal or dated, and you will not be able to tell which slice. Use it for volume and check anything that strikes you as unusual against something written this decade.
What it looks like when it goes wrong
The recognisable failure is a set of near-synonyms collapsed into one. Claim, argue, maintain, suggest and insist all get learned as ways of saying say, and then get used interchangeably, and each of them carries an attitude toward the person being reported. Writing he claimed he was ill where you meant he said he was ill tells your reader you doubt him.
That failure is the one to watch for, because a list is exactly the format that produces it. An entry gives a word and a definition, and near-synonyms get near-identical definitions, so the difference that matters is the one thing the book cannot record.
The band above this one is worth opening only when something specific is waiting behind it, which is academic and low frequency words, for exams and real reading, and how the six are paced against each other is the core word list, worked through one book at a time.
What none of that settles is the difference between the five reporting verbs above, because it is not a difference of meaning at all. It is which words each of them is allowed to stand beside and how much the speaker is committing to: which words English puts together, and which it never does, and then moving what someone said back one step in time.
