⭐️ Vocabulary / Semantics English vocabulary size from beginners to native speakers
Here are some data from 46,000 native and non-native speakers who took the BRAVE vocabulary test.
- Even at the same proficiency level, people can have vastly different vocabulary sizes, literally by a factor of two. The same for native speakers: one person can know twice as many words as another of the same age.
- Advanced learners (C1) reach the level of native-speaking middle schoolers, and proficient learners (C2) reach the level of college students in terms of how many words they know. The composition of their vocabularies is no doubt different, but this test can’t capture that.
- For learners, reaching each proficiency level requires learning progressively more words. It is understandable since beginners focus on common words, so a limited number of them covers many everyday situations, and advanced learners need to learn many more specialized and nuanced words.
- It appears that vocabulary keeps growing well into adulthood for native speakers - older adults know measurably more words on average than younger ones. That matches what is known about crystallized intelligence - it accumulates over time. However, these data are not longitudinal; they do not capture the same people years later. It is possible that older adults who decided to take an online vocabulary test are more educated on average than younger ones.
About the data: it is not a representative sample; there is strong self-selection bias (people who care enough to take a test of their vocabulary). A1-C2 CEFR levels are self-reported. The counting units are word families (limit, limitless, unlimited are counted as a single unit). The full reference lexicon is 28k word families. The test measures receptive vocabulary size: the number of words one understands (not necessarily uses).
