Many of us have struggled when it comes to pronouncing Welsh place names, and it is easy to see how places like Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch could be confusing.
But, a new smartphone app feature has been released which aims to make pronunciation easier.
The new feature, developed by HistoryPoints, uses barcodes placed at hundreds of places of interest around Wales.
By scanning the codes, tablet and smartphone users can access explanations and audio guides for place names.
The information network has also placed codes at viewpoints besides footpaths and roads to help people identify and hear the names of nearby mountains and villages.
There are also explanations for the names of streets, rivers, lakes and even pubs.
