Usage notes
As with many Homeric epithets, this word may not always have a specific or literal meaning in all cases. The lack of any Indo-European etymology adds to the fuzziness. Although it is often used as an epithet for mighty heroes, its frequent use for female humans suggests that its meaning is not exclusively that of heroic strength. In the following example it is clear that some positive moral quality is intended:

But other usages can only be physical. In Odyssey 10.106, Odysseus's men meet a girl who is described as ἰφθίμη:

The meaning here cannot be anything to do with moral nobility, since the girl's mother turns out to be a giant ogress, and her family eat one of the men.
