Kenning
In literature, a kenning is a compound poetic phrase substituted for the usual name of a person or thing. For example, the ocean in Old English was called the whale's road, the whale's-bath, or the sea-street.
The word is derived from the Old Norse phrase kenna eitt við, "to express a thing in terms of another", and is prevalent throughout Norse, Old English and Celtic literature. Kennings are especially associated with the practice of alliterative verse, where they tend to become traditional fixed formulas.
A list of kennings may be consulted for reference purposes.
A notable peculiarity of kennings is the possibility to construct complicated kenning strings by means of consecutive substitution. For example, those who are keen in kenning readily know that slaughter dew worm dance is battle, since slaughter dew is blood, blood worm is sword, and sword dance is battle.
Another kind of wordplay is based on the inversion of kennings. For example, if sword dance is battle and spear-din is another kenning for battle, then sword may easily become "spear-din dancer".
The name "Kenneth" is derived from the same source as kenning, the base word being "ken" and "kin", which is the Rune "K", and means a "kindred" with(as in the words "cunt", "queen" and "king"), and knowledge about something, besides the other word "kindle" and "kindling", which implies illumination, that obviously provides vision. Another few related words are "can", "cunning" and "keen".
