Use suffixes as word-class signals
| Suffix | Original word-family example | Useful inference |
|---|---|---|
| -heit | frei → die Freiheit | A noun naming a quality/state; this derivational suffix is feminine. |
| -keit | zuverlässig → die Zuverlässigkeit | An abstract feminine noun; the base may change shape. |
| -ung | prüfen → die Prüfung | An action/result noun, feminine; not available for every verb. |
| -schaft | Nachbar → die Nachbarschaft | A feminine noun; meaning can include a group or relationship. |
| -bar | prüfen → prüfbar | Often passive possibility: can be checked. |
| -los | Hoffnung → hoffnungslos | An adjective indicating lack; the interpretation can be lexicalized. |
Identify the real suffix, not just the final letters. Der Schaft is a simple masculine noun, not an exception created with the feminine derivational suffix -schaft. Likewise, -bar is not always a transparent “can be” formula: wunderbar is a lexical word. Learn the actual base and meaning. Adjective suffixes do not determine a noun’s gender when the adjective later modifies a noun.
Choose the form and explain the meaning
3. Decode prüfbar in an equipment description.
It can be checked: kann geprüft werden. This is the productive passive-possibility reading.
5. Name the noun related to prüfen. Can every verb use that suffix?
die Prüfung; no. -ung is productive but restricted; learn established derivatives.
7. Why is der Schaft not evidence against feminine derivational -schaft?
Schaft is a lexical base, not a word derived with that suffix. Matching final letters are insufficient.
