def get_declension_attributes(word: object) -> dict[str, str]:
"""
Returns the declension of a word.
If the word does not have a "declension" field or the noun's declension is, for some reasons, "Unknown", this
function returns an empty dictionary.
The declension table is flattened with "declension index" as the map key and the declined form as map value.
Specifically:
- A regular noun declension with a map structure of::
term: der Hut
definition: the hat
declension:
- ["", singular, plural]
- [nominative, Hut, Hüte ]
- [genitive, "Hutes, Huts", Hüte ]
- [dative, Hut, Hüten ]
- [accusative, Hut, Hüte ]
The returned map would be::
{
"declension-0-0": "",
"declension-0-1": "singular",
"declension-0-2": "plural",
"declension-1-0": "nominative",
"declension-1-1": "Hut",
"declension-1-2": "Hüte",
...
}
- A adjectival declension with a map structure of::
term: der Gefangener
definition: (adjectival, male) the prisoner
declension:
strong:
- ["", singular, plural ]
- [nominative, Gefangener, Gefangene ]
- [genitive, Gefangenen, Gefangener]
- [dative, Gefangenem, Gefangenen]
- [accusative, Gefangenen, Gefangene ]
weak:
- ["", singular, plural ]
- [nominative, Gefangene, Gefangenen]
- [genitive, Gefangenen, Gefangenen]
- [dative, Gefangenen, Gefangenen]
- [accusative, Gefangenen, Gefangenen]
mixed:
- ["", singular, plural ]
- [nominative, Gefangener, Gefangenen]
- [genitive, Gefangenen, Gefangenen]
- [dative, Gefangenen, Gefangenen]
- [accusative, Gefangenen, Gefangenen]
The returned map would be::
{
'strong-0-0': '',
'strong-0-1': 'singular',
'strong-0-2': 'plural',
'strong-1-0': 'nominative',
'strong-1-1': 'Gefangener',
'strong-1-2': 'Gefangene',
...
}
:param word: A vocabulary represented in YAML dictionary which has a "declension" key
:return: a flat map containing all the YAML encoded information about the noun excluding term and definition
