I am always urging people to read Kmoch's Pawn Power in Chess, with the same fanatical devotion that a Christian Evangelist reserves for the Holy Bible.
Hans Kmoch: Die Kunst der Bauerfuehrung
I forgot that I wrote already something about the subject https://www.chess.com/forum/view/general/leukopenie
I was asking myself who else tried to use Kmoch's terminology; I never find in my books other authors using most of his terms (only some of them).
I am probably the only guy who thinks that the terminology is useful. We all are used to works like "candidates", "Luft", "Zugzwang", "passed pawns", "pawn chain". We could also say that these terms are not completely necessary, as we could always describe what zugzwang or a passed pawn is. Since we are used to these terms, we are happy to use them. We are able to safe time when we can use specific terms (instead of explaining them all the time).
The problem is not Kmoch's neologism, but the fact that he proposed all these terms in one single work. If these terms would be proposed by several authors during decades and slowly adopted by other chess author, we would today use terms like "sneakers" (an unfree pawn or fake that may become a passer through a sacrificial combination) or "wedge" (two converging chains reaching into enemy territory) without thinking about them as neologisms.
New terms are often used in specialized areas, for example in science, to facilitate communication. If you take a dictionary with biological or medical terms, you will probably perceive them as unnecessary - until you begin to work with biology or medicine.
Here a list from most of Kmoch's terms (I took from another post, who was taken from somewhere in the internet).

And the sealer-sweeper!
Okay, chapter B5 in my German edition, Feldstopfer und Feldfeger. Feldstopfer is a pawn hampering the own pieces. Feldfeger I think is a the pawn which moves to open lines for the own pieces. I didn't read yet the chapter, but I am looking forward to do it.
Did you work seriously with the book? What do you think, did it work for you?
It's hard to say, I read it when I was quite young, when my interest was super-high, and at a point when I was improving quite a bit from playing OTB tournaments every weekend anyway, so how much I actually improved specifically as a direct result of reading it I'm not sure.
However I do think it's an absolutely awesome book and it definitely contained many concepts that I'd not thought about. Some people dislike the terminology but I found it quite charming.
thanks
Recently I went through some pages again...and got completely fascinated by the explanations!
You see here a strong player sharing his huge knowledge on chess, always stressing the role of pawns. He begins with very simple positions, mostly without kings and with few or no other pieces. Later you will see complex positions and how the pawns play a decisive role in the attack, defence, in the fight between minor pieces, etc. If you are afraid that some of his explanations could be corrected by engines...well, use an engine to check the explanations (I am still in the first chapters, and I didn’t tell the need anything with an engine).
This book is universally criticised because the new terminology he proposed.
But weird enough, I like this book ...because this terminology! I am getting use with the new terms, and there are helpful to memorise feature related to pawn formations.
The book is a revelation! I just regret that I didn’t have the stamina to go through it the first time I gave a try.
Although I just began the book (in the last 10 or 15 years I went very superficially through some parts of the book without keeping a simple bit of the knowledge it offers) I can tell you right now that this is my favourite book. And I have a lot of great books in my library!
If you get a copy, remember this: take it easy with the new terms. You will get used to them after going through the first pages. Actually I can imagine that once some of his terms will have a comeback in chess literature.
