It's not just Spain either... Chile uses 'vosotros' as a sort-of-weird version of 'tu' (with some dropped sounds) e.g. 'como estas?' becomes 'como estai?' and sounding like 'como etai?'

Also: tire / tire shop: llanata / llanteria (mexico), neumatico / (tienda de) vulcanizacion (chile). Corn: maiz (mexico), choclo (chile). Car: coche (mexico), auto (chile). etc etc etc

(I'm not latin, I just like traveling there, so dont take the above as gospel :)
