The letter Q has bothered me for a long time. Only before V. And it occured to me that it is a delimiting letter, specifically for V. V is still useful to start words by itself, VADIS, whatever. But Q denotes that it is no longer the component V, from here to down, but the unit. Something that is going from up to down, something that exists, thus a placeholder.
QVA that which stands there with respect to somewhere else.
QVE that which stands there from the perspective of here.
QVI that which stands from the perspective of outside.
QVO the standing thing, now coming down on. What is on is observed.
