We provide a Ultrafast Dictionary Word lookup API
Retrieve Dictionary words using REST API with field filtering flexibility in JSON, XML, TAB, CSV, or TXT format.
The API is designed for consumption with minimal client code.
Our common words pages summarise the definitions and Part of Speech (POS) categories for the most common words in English.
Words can be sorted by frequency or alphabetically.
