   ‎staat (“state”) + ‎-s- + ‎kaping (“hijacking, privateering”) → ‎staatskaping

• Use of the -s- interfix in Afrikaans is based on patterns in the existing vocabulary. It is frequently used after the -ing, -ie and the -er suffixes. It is seldom used following mass nouns.
• The -s- is not used when the previous element end on s: poskantoor. It is not used when the next element begins with s: stadspoort, but stadsaal (no interfix).

-s-

1. Interfix inserted in some compounds.

The usage of fuge-s is phonetically motivated. It is applied on a per-modifier basis, meaning that if the first root generates fuge-s in one compound, it will usually do so in all compounds, even if the second already begins with an s, as in dødsstraf (død + straf) or affaldssæk (affald + sæk).
