Forms

δάκνω (dáknō) [1]

Etymology

It is inherited from Proto-Indo-European *denḱ- (“to bite”).[2][3][1] The aorist δακεῖν (dakeîn) matches the Sanskrit present दशति (dáśati, “bites”) in form, and the Sanskrit perfect and nouns show that the root had a nasal, so that Greek /a/ is its zero grade.[2][4][5] The long vowel of the future δήξομαι (dḗxomai) and the perfect δέδηγμαι (dédēgmai) is a secondary full grade, made after the model of λήψομαι (lḗpsomai) beside λαβεῖν (labeîn).[2][4][6] The present in -νω is a Greek formation on that zero grade.[5]

Cognate with Tocharian B tsāk- (“to bite”), Old High German zangar (“biting, sharp”) and Old Norse tǫng (“tongs”).[2][4]

Ancient grammarians derived it from δήκω (dḗkō), or from καίνω (kaínō, “to kill”) with an intensive prefix.[7]

Earliest recorded meaning

The verb is first found in the Iliad, already in a figurative use: a speech “bit” Hector's heart, that is, stung him.[8][9] Homer also uses it literally of biting.[10]

Semantic evolution

From Homer on it is used of the bites of people, dogs, snakes and insects, and figuratively of whatever stings or hurts the mind: news, events, grief.[10][5] Classical writers use it of biting one's lip to steady oneself or hold back laughter, of a horse champing at the bit, and of smoke stinging the eyes.[10] Compounds with prefixes are many, and the verbal adjective gave more than twenty compounds in -δηκτος, such as ἄδηκτος (ádēktos, “not biting, not bitten”).[5]

In the Septuagint it is used of snakes biting people, in the Book of Numbers, and the New Testament uses it figuratively, together with “devour”, of people who harm one another.[11][12]

Modern Greek δαγκώνω (dagkóno) goes back to a form built on the aorist ἔδακον (édakon): Babiniotis derives it from δακώνω (dakṓnō), with the /k/ voiced after an inserted nasal, and Triantafyllidis from Hellenistic δαγκάνω (dankánō).[13][14][15] Medieval vernacular texts use the newer verb for biting, for insects stinging, and in the Pentateuch translation for lending at interest.[15]
