List of Latin words with English derivatives

This is a list of Latin words with derivatives in English (and other modern languages).

Ancient orthography did not distinguish between i and j or between u and v.[1] Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words. See also Latin phonology and orthography.

Nouns and adjectives edit

The citation form for nouns (the form normally shown in Latin dictionaries) is the Latin nominative singular, but that typically does not exhibit the root form from which English nouns are generally derived.
