fem. proper name, German, literally "battle-maid," from fem. of Old High German hild "war, battle, fight, combat," from Proto-Germanic *hildiz "battle" (source also of Old English (poetic) hild "war, battle," Old Saxon hild, Old High German hilt, Old Norse hildr), from PIE *keldh-, from root *kel- "to strike, cut" (see holt). Hild-/-hild was a common Germanic name-forming element; compare Hildebrand, Brunhild, Matilda.
Old English hild figured widely in kenning compounds: Hildbedd "deathbed;" hildegicel "blood dripping from a sword," literally "battle-icicle;" hildenædre "arrow, lance, spear," literally "war-adder;" hildesæd "weary of fighting, battle-worn," literally "battle-sad."
