What is the etymology of Rus' name? Putting aside Rabbi Yochanan's explanation on Berachot 7b, which may very well not be an etymology at all ( מאי רות א"ר יוחנן שזכתה ויצא ממנה דוד שריוהו להקדוש ברוך הוא בשירות ותשבחות). Some scholars connect Rus to the Moabite רות, which parallels the Hebrew word רעות, friendship, since Moabite did not pronounce and thus eliminated the letter ayin. (I wonder, then, how Rus pronounced her mother-in-law Naomi's name.)there was one post I neglected to mention. What is the relationship to the English word "ruth?" Can we say that Tov, that is, Ploni Almoni, was a ruthless character? :)
In fact, the English word "ruth" has a different etymology. As Webster defines it, it means "compassion for the misery of another," from Middle English ruthe, from ruen to rue. Indeed, this fits nicely into the Biblical Ruth as well.
