Onion Vegetable Ena -- Genuine Doubt

[Force]

Afaik, onion is a leafy vegetable where the bottom of the leaves are bulged, fleshy and used as vegetable. It is rich in sulphur which is the main source in our food. It's not a fruit to be called as kaaya or a root to be called as gadda.just bulged leaf bottom. Hence called as ulli-paayalu which means pile of leaves. That's it.
