greip
Greip is a term that appears in Old Norse literature, most notably in the Poetic Edda. It refers to a specific type of grip or embrace, often with a connotation of strength and possessiveness. In the Eddic poem Grímnismál, Odin, disguised as Grímnir, offers his foster son Agnar a drink from a horn, stating that he will not give him ale again until Agnar has gained "greip" of both the worlds. This usage suggests a metaphorical grasp or understanding of the realms of existence.
The term can also be understood in a more literal sense of physical restraint or capture. In
