Common genealogy terms, including record types, events, dates, and relationships are listed here, along with Latin words with similar meanings (i.e., words commonly used to indicate marriage, including marry, marriage, wedding, wedlock and unite).

Latin Basics

Latin is the mother language for many modern European languages, including English, French, Spanish and Italian. Therefore, Latin will be found used in the earlier records of most European countries, as well as in Roman Catholic records around the world.

Latin Language Essentials

The most important thing to look for in Latin words is the root, as it will give you the basic meaning of the word. The same Latin word may be found with multiple endings, depending on the way the word is used in the sentence.

Different endings will be used if a word is masculine, feminine or neuter, as well as to indicate singular or plural forms of a word. The endings of Latin words can also vary depending on the grammatical usage of the words, with specific endings used to indicate a word used as the subject of the sentence, as a possessive, as the object of a verb, or used with a preposition.
