TYPO3 glossary
A quick reference to the TYPO3 terms you meet when building and running a TYPO3 14 website — for editors, integrators and site owners.
Content Blocks
Content Blocks are the modern way to define custom content elements in TYPO3. Each block bundles its fields, template and configuration in one reusable package — central to TYPO3 14. See our TYPO3 development service.
TypoScript
TypoScript is TYPO3's configuration language. It controls how pages and content are rendered and how the site behaves — without writing PHP.
Fluid
Fluid is TYPO3's templating engine. It separates markup from logic using tags and ViewHelpers; TYPO3 14 ships Fluid 5 with strict typing and reusable components.
Extbase
Extbase is TYPO3's MVC framework for building extensions in a structured, object-oriented way, paired with Fluid for the frontend.
TCA (Table Configuration Array)
The Table Configuration Array (TCA) describes database tables and fields to TYPO3 — how they are edited in the backend, validated and related to each other.
Site Sets
Site Sets are reusable, modular bundles of site configuration (TypoScript, settings, page TSconfig) composed per site — a cornerstone of modern TYPO3 setups.
FAL (File Abstraction Layer)
The File Abstraction Layer manages files and media through a storage abstraction, so assets can live locally or in the cloud and be reused with metadata.
Backend Layout
A Backend Layout defines the column structure of a page — which content areas exist and where — giving editors a clear, consistent grid to place content in.
LTS (Long Term Support)
An LTS release receives bug and security fixes for an extended period. Running a supported LTS — such as TYPO3 14 — keeps your site secure. See our upgrade service.
