Latin Morphological Analyzer and Dictionary
Words has an extensive dictionary of the Latin language as well as the capability to recognize various morphological forms and determine what the root word is as well as the what form it is in. Unlike other apps based on Whitaker's words, this is a port of the original code rather than simply using the dictionary, and therefore essentially feature complete compared to the desktop program.
This app is ad-free, open source, and requires no permissions.
