Terminology

I'm very new to FME and would like to use it to migrate ArcGIS geodatabase feature classes from one geodatabase schema to another. I'm trying to teach myself but am having a little trouble with the terminology in the FME documentation. For instance, it seems to me that the word "attribute" is used in place of "field", at least some of the time. Can someone confirm that's the case? Since I work with GIS data, to me the word "attribute" refers to values in a field, not the field itself, so I am sometimes confused. I need to understand the terminology FME is using but I haven't found an index or dictionary of terms in the FME documentation so far. If one exists I'd be grateful to anyone who can point me to it. Thanks.
