Digital product design involves numerous elements, each with its own terminology. While you might be familiar with design terms like ‘user interface,’ you may not know others, such as ‘user feedback loop.’ Understanding these terms is crucial for staying aligned throughout the design process. Ensuring that everyone—from designers to clients—uses the same language helps facilitate communication. Designers are always ready to explain concepts, but it’s beneficial to do your own research and grasp the basics.
To help you navigate the terminology, we’ve compiled a dictionary of essential product design terms that everyone on the team should know. This glossary is regularly updated with the latest terms, so be sure to revisit it for new additions.
