Really

Really is an approximation of belief.
It must be measured from one point – as a declarative factual statement. On the other end, it can be inflected to register disbelief or uncertainty. You know really. You’ve known it all your life. Really comes from real – reality. It’s an adverb that modifies verbs that pronounce the status, condition or action. Really says it has a relationship to something about life or its perception. Those"perceptions" have dramatically changed because our proximity, speed and our tenuous relationship to the uncertain.

Example.
We could sample some defining modifiers – supposedly actually could be substituted for really; but it doesn’t carry the range of what really can do. Actually keeps its ties to factually. Really takes on that approximated space of reality and not - that we’re comfy with. We could double up – really, really…. Dramatic but redundant. You could go with the total vernacular devastation…really fucking unbelievable…. Exponential is always impressive.
The always New, has come to symbolize better, closer, more convenient, more selection, more options, better deals, new experiences. The New is not a promise for lastingness or permanence.
The continual process of new construction, under construction and renovation, has come to symbolize the fresh state of the New. We have embraced the state of always New. We like the feel of the New, the smell of the New - even the ritualized packaging of the New. We make a place for the New in our lives. We simply prefer, the New. Perhaps, the always New has replaced the old version eternity.
My youngest son Esei gave me another example of really.
His friend Barnes said, "I need to use the restroom."
Esei countered with, "When did you start saying 'restroom' instead of 'bathroom'? Barnes."
"I’ve always said 'restroom'."
Esei. "Oh, really….?"

….life the endless march, an endless army…
The world, the race, the soul – in space and time the universes,
all bound as is befitting each – all surely going somewhere.
- Walt Whittman: Going Somewhere: 1887
