sounds like WHERE-2-GO.. so when you dont know where to go, u feel a SEVERE DIZZINESS out of confusion
Vert represents height. When you look down from a great height, you tend to get dizzy.
Vertigo and tornado have something in common... they both, twirl. Vertigo twirls in your head, making you feel dizzy while a tornado comes like a twirling storm.
When u VERTIcally GO up to some height...u feel, head spinning round and unable to balance i.e DIZZINESS
travelling in vErtigo car in height will make you feel giddiness
vertigo: vert = vertcal , go = fall , so it is fear from falling vertically.
vertex+go.. that u are falling from a vertex .. means u r dizz..
