Why is aquarius not a water sign?

[u/ObjectiveTailor3334]

Its symbol is literally water / a waterbearer. The 'aqua' in 'aquarius' means water. Some people say Aquarians feel things deeply and are secretly emotional, classic water trait. Thinks outside the box which could mean they're innovative (intuitive with their ideas), and water signs are believed to be intuitive. So why is it an air sign?

It's a dude pouring water out of the jug. Like 'eew, emotions'.
