I am trying to find a proper name for forms, that do not exist by themselves, but kinda happen when this word is combined with another to form a compound word, example in Estonian:
ratsionaliseerimine ("rationalizing, rationalization") => Gen. "ratsionaliseerimise" (Genitive is used in compound words for non-basal components of compound)
ettepanek ("suggestion")
but compound word is "ratsionaliseerimis/ettepanek". As you can see, the word final "e" of "ratsionaliseerimise" has been lost due to de-deduplication
How one would call such a form ("ratsionaliseerimis") ?
thanks!
