Savvy is practical.
We're relating in a savvy way when we're applying what we've learned.
Savvy is street-wise.
Growing up all the adults around me focused on my smarts. Yet, I'm a dumb toad compared to AI when it comes to raw smarts. An internet search can give people a vast sampling of different "smarts" far, far beyond what I as a solo brain could ever come up with much less store in my neurons.
Savvy was not a focus. That's not savvy!
For example, it may be "smart" to see ways the world could be different. "If we only ____, then everything would work better!"
But that ain't savvy in a world where people have different incentives and aptitudes, and where predators are looking for prey.
Savvy relating means accepting these "unwanted realities" while exploring shrewd ways to be thriving anyway.
While doing no harm? Wouldn't that be nice!
