Terms 

How to use these terms:

Backend Users
Written as a proper noun when referring to the TYPO3 backend module for managing backend user accounts and groups, found at System > Backend Users. Before the module reorganization in TYPO3 v14, it was listed under "Admin Tools". Lowercase "backend user" still applies when talking about the user accounts themselves, not the module.
Changelog
The collection of per-release Core documentation entries (Breaking Change, Feature, Deprecation, Important) published for each TYPO3 Core version. Also referenced as "Core Changelog". Linked from upgrade guides across many TYPO3 documentation repositories, not just this one.
Classic mode
A TYPO3 installation mode where the full source tree, including the TYPO3 Core and all extensions, lives inside the web root. Contrast with Composer mode, where dependencies are managed by Composer outside the web root.
DB Check
Written as a proper noun when referring to the TYPO3 backend module (provided by typo3/cms-lowlevel ) for checking database consistency and integrity, found at System > DB Check.
Fluid Styled Content
The name of the TYPO3 system extension ( typo3/cms-fluid-styled-content ) that provides the default Fluid-based rendering for content elements. Also used adjectivally, for example "Fluid-Styled Content templates".
Records
Written as a proper noun when referring to the Contents > Records backend module, used to find or create records independently of their page context. Lowercase "records" still applies when talking about database records in general, not the module.
reStructuredText
Use reST as abbreviation.
reST
reStructuredText is a 'Markup Syntax and Parser Component of Docutils'.
TYPO3
Always and everywhere written with capital letters.
third party extension
Do not write "3rd party extension".
