New General Service List

the most important words for second language learners of English

Home to a wide range of free corpus-based word lists and tools for second language learners developed by Dr. Charles Browne, Dr. Brent Culligan and Joe Phillips.


In late 2013, Dr Browne and Dr Culligan analyzed the spoken subsections of the NGSL corpus and published a list of frequencies for spoken English known at the NGSL-S. The 1.0 version contained 822 words which provided up to 90% coverage for spoken English. In 2016, the 1.1 version of the list was published, with slightly better coverage (718 words to reach 90%). In October of 2017 the 1.2 version of the NGSL was released. This list is 721 words and provides up to 90% coverage for unscripted spoken English.
