Translation of "grendel" into English

Gooi net die heeltyd vir die vark stukkies pampoen om hom besig te hou terwyl ek ’n nuwe grendel gaan soek.”

Keep throwing bits of pumpkin to the pig to keep him busy while I go and look for a new bolt.”

Dalk maak die “sterk stad” dan oop en word die “grendel” verwyder van die deur wat tot versoening lei.

Then the “strong town” may be open and the “bar” may be removed from the door to reconciliation.
