Kennings are compound expressions in Old Norse poetry with metaphorical meaning.
Then said Ægir:In how many ways are the terms of skaldship variously phrased, or how many are the essential elements of the skaldic art?Then Bragi answered:The elements into which all poesy is divided are two.Ægir asked:What two?Bragi said:Metaphor and metre.What manner of metaphor is used for skaldic writing?Three are the types of skaldic metaphor.Which?Thus: [first], calling everything by its name; the second type is that which is called 'substitution;' the third type of metaphor is that which is called 'periphrasis,' and this type is employed in such manner: Suppose I take Odin, or Thor, or Týr, or any of the Æsir or Elves; and to any of them whom I mention, I add the name of a property of some other of the Æsir, or I record certain works of his. Thereupon he becomes owner of the name, and not the one whose name was applied to him: just as when we speak of Victory-Týr, or Týr of the Hanged, or Týr of Cargoes: that then becomes Odin's name: and we call these periphrastic names. So also with the title Týr of the Wain.
Snorri then lists a great many poetic periphrases, although not all are actually used in poems and may be of his own invention. Some concern the gods, others relate to war and weapons, and yet others to everyday objects:

For example, in a verse by the tenth-century Icelandic skald Eysteinn Valdason, "Þrúðr's Father" (i.e. Thor) hauled up the "sea-road's circler" (i.e. Jörmungandr) aboard his vessel:
- With glowing eyes Thrúdr's Father
Glared at the sea-road's circler,
Ere the fishes' watery dwelling
Flowed in, the boat confounding.
Some kennings are a compound of two other kennings, such Fish-road Steed for ship. More poetic circumlocutions can be found in the eddic poem Alvíssmál.
From Old Norse kenna, "know, perceive."
