soinnittomien
Soinnittomien is the genitive plural form of the Finnish adjective soinnittomat, a term used in phonology to refer to the class of voiceless or unvoiced consonants. In linguistic descriptions, soinnittomien is used to describe the set of consonants produced without vocal fold vibration, as opposed to soinnilliset consonants, which involve voicing. The distinction between voiceless and voiced consonants is a standard part of describing Finnish phonology, even though it does not function as a full phonemic contrast for most native words.
In standard Finnish, many native consonants are unvoiced, such as p, t, k, f, s, and h.
The term soinnittomien is most commonly encountered in linguistic descriptions, grammars, and dictionaries when grouping consonants
