New General Service List
A modern corpus-derived replacement for West's General Service List, comprising approximately 2,800 high-frequency English headwords. Released in March 2013 — the sixtieth anniversary of West's 1953 list — by Charles Browne, Brent Culligan, and Joseph Phillips, with the canonical home at newgeneralservicelist.org.
Background
By the early 2000s the General Service List had become difficult to defend on three grounds: a small, hand-counted corpus from the 1930s; written-only sources; and lexical gaps in contemporary technology, media, and global topics. Browne, Culligan, and Phillips set out to rebuild a general-service list with a much larger modern corpus while keeping the original goal — the smallest set of words that gives the highest text coverage for a general learner of English.
Composition
The NGSL is derived from a 273-million-word subsection of the two-billion-word Cambridge English Corpus, sampled across spoken and written genres. Headwords are presented as lemmas rather than full Bauer-and-Nation word families, a choice the authors argue keeps the list more transparent for classroom use. The list is distributed as an Excel spreadsheet ranked by frequency, with derived sublists at 1,000-word bands. Companion resources include the NGSL-Spoken (NGSL-S), NGSL Test (NGSLT), and a frequency-aligned readability tool.
Coverage Claims
The authors report that the NGSL provides approximately 92% coverage of most general English texts, the highest reported figure for any corpus-derived general English word list at that size. By comparison, the original GSL is typically cited at 84–86% coverage of comparable contemporary text samples. Independent evaluation by Stoeckel and colleagues confirms the coverage claim while noting that exact figures depend on corpus and counting unit.
Use in ELT
The NGSL underlies the lemmatised graded-reader scheme used by several Japan-based publishers, drives vocabulary profilers such as the AntWordProfiler NGSL setting, and is widely adopted in Asia for syllabus scoping in adult and tertiary EFL. It pairs with the New Academic Word List for EAP contexts in the same way West's GSL pairs with Coxhead's Academic Word List. Nation's BNC COCA Headword Lists (2K 3K 4K) remains the principal alternative, with ongoing debate over family-vs-lemma counting and the most useful unit for course design.
