So lets say I am talking about the thickness of different layers, would I say:

The different layer thicknesses are causing a problem in production.

or

The difference in thickness of the layers are causing a problem in production.

Is "thicknesses" even a real word?

It has no plural although being a noun.


"The cake has multiple layers of varying thickness."

I believe you just use "thickness" even for plural use.

"The different layers, a, b, and c have thickness, 10,9, and 5 respectively.

I believe you would make "difference" plural. That first thing you wrote makes no sense, even if "thicknesses" is a word.

so it should be , "thickii"

Don't be stupid. "ii" is for words that end in "us", for words that end in "ness" its "ee".

So the correct way to say that is "The thicknee of different layers..."

Henry Jones Sr. voice: But in Latin, "i" is pronounced "ee"... oh dear.

Just say "The difference in layer thickness is..." and be certain.

Not to be an ass, but as your post shows, just because it isn't underlined in red doesn't mean it's grammatically correct.

Drop it into MS Word. If it doesn't have the red squiggle then it MUST be a real word.

Thicknesses is a word.

I'm very disappointed that those among you who didn't know couldn't even google it to find that out.

Thicknessess is a word. The first sentence is fine gramatically. However, because the focus is on the differences in the thickness of the layer, and not on the specific thicknesses themselves, you should use a sentence where "differences" is pluralized.

"The differences in layer thickness are causing a problem in production."

It's also easier to read as "thicknesses" is a bizarre, cumbersome word.
