How were kennings used in Old English poetry?

In Old English poetry, a kenning served as a concise, figurative phrase or compound noun used to replace a common noun. These metaphorical expressions were a standard device within the highly formulaic tradition of alliterative verse, helping poets depict scenery and characters through recurring, culturally resonant imagery.123

Common examples include:
* Swan-road or whale-path for the sea123
* God’s beacon for the sun1
* Ring-giver for a king1

Derived from the Old Norse word kenna—meaning to perceive, know, or name—kennings functioned as allusions that enriched the cultural depth of the work. Because Old English poetry relied on a shared set of stock phrases and patterns, these devices remained consistent for centuries, reflecting the extreme conservatism of Anglo-Saxon literary culture. While some kennings are straightforward, others are complex allusions that may be difficult for modern readers to interpret without context.13
