## What it is
pymorphy2 is a Python library providing morphological analysis (POS tagging and inflection) for Russian and Ukrainian languages. It includes dictionaries based on OpenCorpora and supports word form generation and parsing.

## Use cases
- lemmatize Russian words in a text processing pipeline
- get part-of-speech tags for Ukrainian text
- inflect Russian nouns into different grammatical cases
- normalize words for search indexing
- analyze word forms in Slavic languages from Python

## When to choose
- you need fast, offline morphological analysis for Russian or Ukrainian
- you want a lightweight pure-Python library with dictionary-based accuracy
- you need word inflection/generation, not just tagging

## When to avoid
- you need morphological analysis for languages other than Russian or Ukrainian
- you need a maintained general-purpose NLP toolkit with broad language support
- you require active development or frequent updates

## Facets
- artifact type: library

- function: nlp, parser
- domain: developer-tools
- platform: python, cross-platform
- tags: morphological-analysis, pos-tagger, inflection, russian-language, ukrainian-language, opencorpora, natural-language-processing
