In learning to read Portuguese records, it is very helpful to know and be able to recognize certain words common to the records. The Portuguese Genealogical Word List is now on the FamilySearch.org website in its entirety. It includes keywords you will encounter as well as numbers, dates, days of the week, and a general word list. In Portuguese records, you will find that most numbers, including dates, are written out in the Cardinal format and the numbers are spelled out in the records rather than written as numbers.
