If this document does not provide the guidance you need, use the following sources of information.
The English language is always evolving, changing, and surprising us. While we've tried to cover as much as we can in this guide, there's always more we missed. Here are some key resources used at Arm to help you write dazzling, effective, and grammatically correct content.
[01] The Associated Press Style Book
The Associated Press Style Book is the primary reference for questions on editorial style (we have noted instances where Arm style differs from AP throughout this guide). The Associated Press Stylebook online is subscription only, but the AP’s FAQ forum is available to all users and offers answers to style, spelling, and grammar questions.
For Arm technical documentation, the Chicago Manual of Style 2017 is the primary reference for questions on editorial style. Arm has a corporate subscription you can access here.
Arm has two main glossaries to help you navigate the terminology accurately. The main arm.com website is home to this Glossary Index, and the more technical and extensive Arm Glossary is available on the Arm Developer website.
Codenames is an informal but popular record, also accessible through Confluence.
[04] Merriam-Webster Dictionary
Merriam-Webster is the Arm reference for questions on the meaning and spelling of words.
