English Academic Vocabulary

Level: C1. Academic English is not harder words for their own sake — it is precise, neutral, and cautious. This page gathers the research verbs, idea nouns and formal linkers you need for essays, reports and presentations, grouped by the job they do in an argument, each with a plain meaning and a model sentence you can adapt.

By the end of this page you can…

…choose a precise research verb, name an idea with the right noun, link clauses with formal connectors, and hedge a claim so it is accurate rather than overstated.

How this list was chosen

Every word here comes from the English frequency list (hermitdave/FrequencyWords), which ranks words by how often they appear in a large collection of everyday subtitles. From that list we kept the words that do academic work — reporting research, naming ideas, and linking arguments — and grouped them by function rather than by rank. The Rank column is the word’s real position in the list: a lower number means more common. Notice how high the numbers are here: academic words are rarer in everyday speech because they belong to writing and formal talk, so a high rank is expected, not a mistake.
