Hi @deltasalmon,
Sometimes adding new meanings to newly encountered words can be tricky (with the differences between mobile and the web browser), so I wanted to make sure.
Have you tried these steps and is it still not working for you?:
- Navigating to the page you want → clicking on the blue word you want to define:
- Clicking on the arrow down carrot
:
- Typing into the “Type a new meaning here” box:
- Hitting your enter/return key so the new meaning displays like this (grey in color):
Note: I included a bit more info in case a future user might benefit from these screenshots, not saying you missed something. (I hope that’s clear. 
)
Just because: Images for Users wanting to add a new meaning to a word via mobile (Android)
- Navigate to the page you want → click on the blue word you want to define:
- Swipe up on the popup box for the new blue word you clicked:
- Type in the New Meaning of your clicked-blue word in the “Type new meaning here” box:
- Click the check mark to confirm your new meaning (

Note: Directions included to help others (if they need it) because it took a bit for me to figure out the shortcut of swiping up on the popup, lol. Please ignore if this is unhelpful to your use case.
