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.

THE Business SERVICE LIST 1.01

On this page we will put various resources related to the new Business Service List (Browne, C. & Culligan, B., 2016), also known as the BSL 1.01. It is based on an approximately 64 million word corpus of business texts, newspapers, journals and websites, with a breakdown as follows:

The 1700 words of the BSL 1.01 version gives up to 97% coverage of general business English materials when combined with the 2800 words of the NGSL.

As with our NGSL, NAWL and TSL word lists, we will be working hard to create and support the creation of a wide range of free tools for students, teachers, researchers and materials developers to better utilise the BSL. The Business Service List and definitions are made available to you under the least restrictive Creative Commons license, meaning you are free to use or modify the list in any way you see fit as long as you give proper citation to the authors of the list.

If you create a useful online tool with the BSL please let us know so we can post a link and help spread the word.
