Decision gist · record as of 2026-08-14
Yes. This is a stable, dependency-free utility for a common NLP task. Install friction is minimal, maintenance is active, the license is permissive, and there are no known vulnerabilities. Use it if you need stopwords for any of the supported languages in a text processing workflow.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction with no runtime dependencies.
- Actively maintained with a recent release (38 days ago) and support for current Python versions (3.10–3.14).

What it is and what it does
stopwordsiso is a Python wrapper around a multilingual stopwords dataset, organized by ISO 639-1 language codes. It provides a simple API to check if a language is supported and retrieve its stopword set. The package bundles precompiled stopword lists in JSON format and exposes them through two main functions: `has_lang()` to test language availability and `stopwords()` to fetch word sets by language code or list of codes. It has no external runtime dependencies, making it lightweight and easy to integrate into text processing pipelines.
The stopwords themselves are maintained upstream in a separate project; this package acts as a Python distribution layer. It supports modern Python versions (3.10 through 3.14) and is actively maintained. The data is permissively licensed under MIT, so you can use and redistribute it freely.
Use it for
- Filter common English or multilingual stopwords from text before NLP analysis or search indexing.
- Preprocess documents in multiple languages for machine learning by removing language-specific filler words.
- Build language-aware text cleaning pipelines that handle German, Indonesian, Chinese, and other supported languages.
- Reduce noise in text classification or sentiment analysis by excluding words that add little semantic value.
- Support multilingual search applications by removing stopwords before indexing or querying.
