- progressive participle suffix
- As with the agentive particles in other Mongolic languages, forms built using this suffix can also be used to derive names of occupations.
- The primary usage is to form relative clauses which denote an ongoing event relative to the rest of the sentence.
-chen n (genitive -chens, plural -chen)
- nowadays the most common German suffix to create a diminutive form
- Words ending in the suffix -chen are always neuter, whatever gender the basic word.
- Generally, with few exceptions, diminutives with -chen have an umlauted stem vowel. Double vowels must be singled as the combinations ää and öö are not permitted in modern German orthography (e.g. Härchen from Haar, Bötchen from Boot).
- Words ending in -ch (and some others) use the double suffix -elchen, e.g. Strichelchen from Strich. However, the suffix -lein is quite common for these words in writing (Strichlein).
- Some words also have a (dated or colloquial) plural in -erchen, e.g. Häuschen, Hühnchen, Kindchen, Lämmchen, Liedchen, Männchen.
