But sometimes, categorisation can take place without affixation, and when this happens, we call this type of categorisation zero-derivation, or conversion.

This type of affixation is also attested in German: ge-sing-e (singing), for example, is derived from sing (to sing) and ge-lieb-t (loved) from lieb (to love).

类型的词缀加在德语中也得到了证实：例如，ge-sing-e（正在唱歌）是从sing（唱歌）衍生出来的，ge-lieb-t（被爱的）是从lieb（爱）衍生出来的。
