PyMorphy3 is a morphological analyzer (POS tagger + inflection engine) for the Russian language. It provides tools for parsing words, getting normal forms, and inflecting words into various grammatical forms. The current version is 2.0.6, and the library is actively maintained with frequent minor releases to support new Python versions and address issues.

MorphAnalyzer

✓ from pymorphy3 import MorphAnalyzer

✗ from pymorphy3.analyzer import MorphAnalyzer

The MorphAnalyzer class is now directly available at the top-level package for simplicity.

Initializes the MorphAnalyzer and demonstrates parsing a word to get its grammatical tag and normal form, then inflecting it to a different case.

import pymorphy3 morph = pymorphy3.MorphAnalyzer() # Parse a word word_analysis = morph.parse('стали')[0] print(f"Word: {word_analysis.word}") print(f"Tag: {word_analysis.tag}") print(f"Normal form: {word_analysis.normal_form}") # Inflect a word to a different form inflected_word = word_analysis.inflect({'sing', 'datv'}) if inflected_word: print(f"Inflected form (singular, dative): {inflected_word.word}")

Debug

Known issues

breakingSupport for Python 2 and Python 3.5 was officially dropped in version 2.0.0. If you are using these Python versions, you must stick to `pymorphy3 < 2.0.0` or upgrade your Python environment.

fix

Upgrade your Python interpreter to 3.6 or higher, or pin `pymorphy3` to `<2.0.0`.

affects: >=2.0.0

breakingThe `restore_word_case` function was removed in version 2.0.5 due to cleanup and deprecation. Code relying on this function will fail.

fix

Remove calls to `restore_word_case`. You may need to handle word casing manually or derive it from the `lexeme` property of a `Parse` object if applicable.

affects: >=2.0.5

gotchaFor improved performance, especially with large texts, PyMorphy3 offers C-extension based 'fast' extras. These require Python 3.9+ and installing with `pymorphy3[fast]`.

fix

Install with `pip install 'pymorphy3[fast]' pymorphy3-dicts-ru` to enable C-extensions for faster processing on supported Python versions.

affects: >=2.0.3

gotchaThe command-line interface (CLI) dependency was switched from `docopt` to `Click` in version 1.3.0, making `Click` an optional dependency. If you use `pymorphy3` from the command line, you might encounter issues if `Click` is not installed.

fix

Ensure `Click` is installed if you use the CLI tools: `pip install pymorphy3[cli]` (or `pip install Click`).

affects: >=1.3.0
