morphkit.decode_tag

morphkit.decode_tag(tag_input: str, debug: bool = False) → Dict[str, Any]

Decode a morphological tag into a set of human-readable features.

This function takes a morphological tag (e.g. “V-PAI-3S”) and returns a dictionary of interpreted grammatical properties, such as Part of Speech, case, number, gender, tense, voice, mood, person, and any suffix details.

Args:

tag_input (str):

The raw morphological tag string. Usually includes prefixes like “N-”, “V-”, “A-”, etc., followed by coded letters/numbers.

debug (bool):

Optional argument. Defaults to False. If set to True the function print some debug information.

Returns:

Dict[str, Any]:

A mapping from feature names to their full descriptions.

Possible keys include:

• “Part of Speech”

• “Case”, “Number”, “Gender”

• “Tense”, “Voice”, “Mood”

• “Verb Extra” or “Suffix”

• “Warning”, warning related to feature elements

• “Error” (e.g., if input is empty)

If the part of speech can not be determined, it returns {“Part of Speech”: “Unknown or Unsupported”}.

If tag_input is empty or whitespace, it returns {“Error”: “Please enter a parsing tag.”}.

Example:

morphkit.decode_tag("N-NSM")
{
    "Part of Speech": "Noun",
    "Case": "Nominative",
    "Number": "Singular",
    "Gender": "Masculine",
    ...
}
