Wn is a Python library for exploring information in wordnets. Install it from PyPI and download some data:

$ pip install wn
$ python -m wn download oewn:2021  # the Open English WordNet 2021

Then start exploring:

>>> import wn
>>> en = wn.Wordnet('oewn:2021')  # Create Wordnet object to query
>>> ss = en.synsets('win')[0]     # Get the first synset for 'win'
>>> ss.definition()               # Get the synset's definition
'be the winner in a contest or competition; be victorious'


Available Wordnets

Any WN-LMF-formatted wordnet can be added to Wn's database from a local file or remote URL, but Wn also maintains an index (see wn/index.toml) of available projects, similar to a package manager for software, to aid in the discovery and downloading of new wordnets. The projects in this index are listed below.

English Wordnets

There are several English wordnets available. In general it is recommended to use the latest Open English Wordnet, but if you have stricter compatibility needs for, e.g., experiment replicability, you may try the OMW English Wordnet based on WordNet 3.0 (compatible with the Princeton WordNet 3.0 and with the NLTK), or OpenWordnet-EN (for use with the Portuguese wordnet OpenWordnet-PT).

Open Wordnet (OWN) Collection

The Open Wordnets for Portuguese and English collection (own:1.0.0) installs the following lexicons (from here) which can also be downloaded and installed independently:

Name Specifier # Synsets Language
OpenWordnet-PT own-pt:1.0.0 52670 Portuguese [pt]
OpenWordnet-EN own-en:1.0.0 117659 English [en]

Collaborative Interlingual Index

While not a wordnet, the Collaborative Interlingual Index (CILI) represents the interlingual backbone of many wordnets. Wn, including interlingual queries, will function without CILI loaded, but adding it to the database makes available the full list of concepts, their status (active, deprecated, etc.), and their definitions.

Name Specifier # Concepts
Collaborative Interlingual Index cili:1.0 117659

Changes to the Index


The 2021 version of the Open English WordNet (oewn:2021) has changed its lexicon ID from ewn to oewn, so the index is updated accordingly. The previous versions are still available as ewn:2019 and ewn:2020.

pwnomw-en, omw-en31

The wordnet formerly called the Princeton WordNet (pwn:3.0, pwn:3.1) is now called the OMW English Wordnet based on WordNet 3.0 (omw-en) and the OMW English Wordnet based on WordNet 3.1 (omw-en31). This is more accurate, as it is a OMW-produced derivative of the original WordNet data, and it also avoids license or trademark issues.

*wnomw-* for OMW wordnets

All OMW wordnets have changed their ID scheme from ...wn to omw-.. and the version no longer includes +omw (e.g., bulwn:1.3+omw is now omw-bg:1.4).
