Gerim

In Rabbinic times the definition of a ger varied.
Thus, there were: 


1. the Ger Tzedek, the “just” or full ger, who willingly lived as a Jew in all respects and observed all the commandments;

2. the Ger Toshav, the “resident ger,” who lived among Jews and, though not fully observant, renounced idolatry and other pagan practices; 

3. the Ger Arayot or “lions’ ger,” who accepted Judaism out of superstition rather than informed conviction (based on the story in Kings II about how the Samaritans, the people brought to Samaria after the exile of its Israelite inhabitants by the Assyrians, began to worship the Israelite G-d, because they thought He was the reason for the lion attacks);

4. the Ger Ester u’Mordekhai, the “Esther-and-Mordecai ger,” who converted in fear of Jewish violence or persecution (based on the last chapter in the book of Esther);

5. the Ger To’eh or “errant ger,” who practiced Judaism on his own and incorrectly;

6. the Ger Garur, the “[self]-attached ger,” who considered himself a Jew because he associated with Jews, even though they themselves did not think of him as such.
