Aether and Amberite in the Cosmere

The main character notes that these two elements both have growth in common or we might say progression yeah i definitely was getting window vibes from the verdant user. You can never hide it fully exactly and i found that an interesting aspect but let's continue down so that's the first of the pairings with growth in common what are the next two? The next two are ferris which is metal ability and i don't know it's not shown if there's like a medium aspect of ferris.
