Looking at board layouts, I often see a capacitor stacked above a resistor using the same two eyelets/turrets. My question is...if you had room for three eyelets/turrets, could you place the two componets in series, with the cap and resistor sharing the middle of the three eyelets/turrets?

Can you draw us a picture with the components in a circuit?

I think you're most likely describing cathode resistor/cap. Those two components are connected in parallel and cannot be put in series using three turrets as you suggest.

The number of turrets used has no importance as long as the connections (series or parallel) are respected

Yes. And the term "stacked" has its own meaning, not applicable here. In sluckey's example, the resistor is said to be "bypassed" by the cap. The term "stacked" is inapplicable.
Some people like to stack caps. That's using 2 different types of caps in parallel to add up to the desired value -- such as an oil cap + a plastic cap. This is done for tonal purposes.
But 2 resistors in parallel are not said to be stacked. They're just in parallel. It's a nomenclature thing.

"I often see a capacitor stacked above a resistor using the same two eyelets/turrets."
I took that statement literally. I call it stacking too. Exactly like the three stacked cathode R/Cs in this pic...

And sometimes I stack the resistor on top of the cap, like the three stacked cathode R/Cs in this pic...

Thank you all for your help.
A cathode capacitor/resistor "bypass", as seen on the far right of slucky's 6v6plexi pic, is exactly what I was trying to describe.

Ok, but on a roomier board you may have placed these same components side-by-side. Then I guess we could say that they've gotten laid horizontally. :icon_biggrin:
This brings out the distinction between layout vs. schematic. It has been declared (somewhere, sometime long ago) that the schematic shall prevail. Per layout, using the term stacked for components placed side-by-side vertically seems appealing. But the term stacked would be confusing for the same 2 components placed side-by-side.
A tonestack is called a stack, because of the way it's conventionally drawn on a schematic. Per layout, those components may be all over the place, but not visually stacked at all.

Of course. I swing that way too! :icon_biggrin:

Hmm. Not at all confusing to me.
I'm just a country boy. When you tell me to stack stuff, I'm gonna put one on top of the other. Lot of other country boys know what that means too. :icon_biggrin:

Well you can stack it, but if it comes a rain, you best roll your pants up. Then it becomes a pile.
Roll you britches up country boy, anem gnats are just South Alabama ground pepper. Go goes good on the Alabama steak.

If it is the Horizontal Bop as JJ refers and to be laid, you would have to be horizontal. Is there a vertical bop and if so, are you getting laid or are you getting stand?
All this tech stuff confuses me!

are you getting laid or are you getting stand?
