@kengaroo - What you call 'extension' is what makes a verb into a noun; it's an 'affix'. you have quoted lots of abstract nouns in your example, interestingly all those are from the French

the ance, ence endings are from the French - in French (and many other languages too) how the word stem sounds has in the past determined the 'ence' or 'ance' ending - later, changes happened in French too, and conventions remained, even if they no longer made sense, but they got taken here by the Normans (William the Conqueror made everyone speak French, but the 'lower staff' like nannies, wet nurses, servants etc. were humble English folk and managed to sneak their native language into the Conquerors' - and it has been incorporated into what we now call 'English' and it has become one of the richest languages - and to my mind one of the simplest, but capable of so much expression.
