C1 Academic English Vocabulary: Precision Verbs, Hedging and Register
This C1 Academic English Vocabulary module covers 55 words for arguing carefully in writing — the verbs that do the real work (underpin, substantiate, corroborate, refute, concede, undermine), the linking words that shape a paragraph (conversely, notwithstanding, albeit, thereby), and the nouns an argument is built from: premise, rationale, caveat, nuance, paradigm. Every word comes with flashcards, a word-formation drill, a collocations match and a twelve-question quiz, free and self-scoring.

What’s inside this module
Four stages: meet the words, build other forms from them, pair them with the words they normally go with, then test yourself.
Flashcards
Fifty-five cards, each with the word, its part of speech, a precise C1 definition, an example sentence, and two typical collocations on the back — mitigate the effects, encompass a range, reach a consensus. Rate each card “I knew it” or “Still learning” and your ratings are saved automatically.
Word formation
Eight gap sentences that ask for a different form of a word you have just met: coherent becomes coherence, infer becomes inference, concede becomes concession, plausible becomes plausibility, prevalent becomes prevalence. Abstract nouns are most of the work at this level.
Collocations & phrases
Ten pairs taken from how the words are actually used in academic prose: reach a consensus, a null hypothesis, a conceptual framework, a false premise, a glaring discrepancy, an important caveat, evidence to substantiate.
12-question quiz
A mix of multiple choice and fill-in-the-blank, with an explanation after every answer, right or wrong. Your best score is saved automatically.
How to get the most from it
Five habits that make C1 vocabulary stick, not just pass a quiz.
Hedging is a skill, not a weakness
Arguably, ostensibly, plausible and to a certain extent let you make a claim without overstating it. Academic English rarely says that something is simply true, and a writer who states everything flatly reads as less careful rather than more confident.
The verbs are not interchangeable
Corroborate is not substantiate, and concede is not refute. Each verb describes one specific move in an argument — supporting it, proving it, admitting a point, rejecting a point. Learn what each one does to the argument, not just its translation.
Register is the whole point
Notwithstanding, albeit, hence and thereby belong to formal writing and sound strange out loud. Using one in conversation is as noticeable as dropping a casual phrase into a research paper, and controlling that difference is a large part of what C1 means.
Come back for the re-deal
After you finish the flashcard deck, it automatically rebuilds itself from just the words marked “still learning.” A short second pass on the hard ones is worth more than repeating the whole deck.
Use one this week
Take a paragraph you have already written and rewrite it using three words from this deck: one hedge, one argument verb, one linking word. Rewriting your own sentences shows you exactly where the vocabulary fits and where it does not.
