Simple definition
A WordPress block pattern provides a predefined arrangement of blocks for reuse in content.
Purpose and use
A block pattern provides a ready-to-insert arrangement, such as a banner, grid or introductory section.
How does it work?
An unsynced pattern creates blocks that can be edited independently after insertion. A synced pattern retains shared content.
Example and verification
Before reusing a section, decide whether changes should remain local to the page or affect its other uses.
Points to watch
The same visual design on multiple pages does not prove they share a synced pattern.
In short
Choosing independent copies or shared content determines the scope of subsequent edits.
