Notes (1)
[1] Used mainly by Christian writers in reference to Jesus’ incarnation (though LSJ s.v. cites an instance from Heliodorus: Aethiopica 2.31.1). For the substantive e)nanqrw/phsis see under epsilon 2102 and upsilon 482.
2This obscure remark may refer to the way this verb is augmented in historical tenses, especially the aorist e)nhnqrw/phsa. See epsilon 1315, and generally Lampe s.v.
