Folk etymology is a long-lived tradition empowering writers to fabricate etymological explanations to suit their current interpretive and argumentative needs.
Here’s what those joyless pedants of the Oxford English Dictionary have to say about it:
Just in case you were wondering, the ancient Romans and Greeks did have the concept of procrastination. Here are some passages I collected about it.
But where would we be without hermeneutically adventurous lexicography? Plato makes it a centerpiece of his Cratylus! And we have dictionaries dedicated to it:
“Lipless Achilles” Kallierges, Etymologicum Magnum 182
“Akhilleus: [this name comes from] lessening grief, for Achilles was a doctor. Or it is because of the woe, which is pain, he brought to his mother and the Trojans. Or it is from not touching his lips to food [khilê]. For he had no serving of milk at all, but was fed with stag-marrow by Kheiron. This is why he was hailed by the Myrmidons in the following way, according to Euphoriôn:
He came to Phthia without ever tasting any food
This is why the Myrmidons named him Achilles.”
᾿Αχιλλεύς: Παρὰ τὸ ἄχος λύειν· ἰατρὸς γὰρ ἦν. ῍Η διὰ τὸ ἄχος (ὅ ἐστι λύπην) ἐπενεγκεῖν τῇ μητρὶ καὶ τοῖς ᾿Ιλιεῦσιν. ῍Η διὰ τὸ μὴ θίγειν χείλεσι χιλῆς, ὅ ἐστι τροφῆς· ὅλως γὰρ οὐ μετέσχε γάλακτος, ἀλλὰ μυελοῖς ἐλάφων ἐτράφη ὑπὸ Χείρωνος. ῞Οτι ὑπὸ Μυρμιδόνων ἐκλήθη, καθά φησιν Εὐφορίων,
᾿Ες Φθίην χιλοῖο κατήϊε πάμπαν ἄπαστος.
τοὔνεκα Μυρμιδόνες μιν ᾿Αχιλέα φημίξαντο.
Odysseus Was Born on the Road in the Rain: Kallierges, Etymologicum Magnum 615
“The name Odysseus has been explained through the following story. For they claim that when Antikleia, Odysseus’ mother, was pregnant she was travelling [hodeuousan] on Mt. Neritos in Ithaka, and it began to rain [husantos] terribly Because of her labor and fear she collapsed and gave birth to Odysseus there. So, he obtained is name in this way, since Zeus, on the road [hodon] rained [hûsen].”
᾿Οδυσσεύς: Εἴρηται ἀπὸ ἱστορίας. ᾿Αντίκλειαν γάρ φασι τὴν ᾿Οδυσσέως μητέρα ἐγκύμονα ὁδεύουσαν τὸ Νήριτον τῆς ᾿Ιθάκης ὄρος, ὕσαντος πολὺ τοῦ Διὸς, ὑπὸ ἀγωνίας τε καὶ φόβου καταπεσοῦσαν ἀποτεκεῖν τὸν ᾿Οδυσσέα. Οὕτω ταύτης τῆς ὀνομασίας ἔτυχεν, ἐπειδὴ κατὰ τὴν ὁδὸν ὗσεν ὁ Ζεύς.
It is more typical to derive Odysseus’ name from the verb odussomai, which means something like “being hateful, being hated”. Autolykos, Odysseus’ maternal grandfather, is reported to have named him in the Odyssey (19.407–409).
“I have come to this point hated [odussamenos] by many—
Both men and women over the man-nourishing earth.
So let his name be Ody[s]seus…”
πολλοῖσιν γὰρ ἐγώ γε ὀδυσσάμενος τόδ’ ἱκάνω,
ἀνδράσιν ἠδὲ γυναιξὶν ἀνὰ χθόνα βωτιάνειραν·
τῷ δ’ ᾿Οδυσεὺς ὄνομ’ ἔστω ἐπώνυμον…
