Microsoft has pushed a new Chromium Edge Build
Here is how Microsoft had described Picture dictionary feature on the legacy Edge.
We are excited to announce the rollout of the Picture Dictionary capability built in directly to the Immersive Reader. The ability to see a picture and see and hear the word simultaneously (multi-sensory processing) is a technique to aid reading and comprehension. With the Picture Dictionary, a student can click on a word and immediately see a related picture, and have the ability to “Read Aloud” as many times as necessary. Students also now have the ability to click on any single word and have it read aloud. These pictures have been provided in partnership with Tobii Dynavox, one of the world’s leading symbols companies and creator of Boardmaker.
Below pictures show how it looks like on the Chromium Edge.
this new option added to Edge Version 83.0.461.1 (Official build) canary (64-bit)
simply double click on a word and a picture will appear showing you what it means
