Recently I stumbled accross a definition of how to use the Instrumental in Russian. It is very detailed and lays out very many different possibilities in a systematic way. It talks about the "Instrumental of means", "Instrumental of adjunction", etc. etc. but it never mentions a so called "Instrumental of manner", which I found later in a book about Ukrainian grammar.
An example from the book about Ukrainian would be:
говорити ніжним голосом
meaning "to speak in a soft voice."
Now I wonder if this can also be done with the Instrumental case in Russian or if this is specific to Ukrainian.
PS: I do not speak a word of Russian or Ukrainian, my interest comes from a purely linguistic perspective.
