Single s in prevocalic position is pronounced, except when it follows an obstruent within the word stem (e.g. , , , ). is usually retained in recent borrowings from English (e.g. ), to a lesser degree also in recent borrowings from other languages (e.g. ). Words from the classical languages and pre-1900 loanwords behave like native words.

Stem-initial st and sp are pronounced and  in native words. The same is generally true for classical and pre-1900 loanwords, though in this case we find some exceptions which are at least optionally pronounced with (e.g., ). Recent borrowings tend to retain the original sounds. Again, this tendency is stronger with English than with other source languages (cf. e.g. with ).

The trigraph sch is pronounced, except when there is an intervening morpheme boundary, which normally happens only with the diminutive suffix (cf. e.g. ).

Otherwise, pre-consonantal and word-final s is always pronounced. This also includes st, sp when they are not stem-initial. The same is generally true for doubled ss. There are, however, a few words in which ss may – optionally – be pronounced (e.g., , , ). For the orthographic choice between ss and, see the latter.
