hurtle

The verb is derived from Middle English hurtelen, hurtlen (“to cast, hurl, throw; to charge at; to clash in combat, fight; to collide; to injure; to knock down; to propel, push, thrust; to rush; to stumble”) [and other forms], from hurten (“to injure, wound, hurt (physically or figuratively); to damage, impair; to hurt one’s feelings, humiliate; to receive an injury; to collide into; to propel, push, thrust; to stumble”) (see further at English hurt (verb)) + -el-, -elen (frequentative suffix). The English word is analysable as hurt (“(obsolete) to knock; to strike”) +‎ -le (frequentative suffix).

The noun is derived from the verb.

Possibly a clipping of hurtleberry, from Middle English hurtil-beri (“bilberry or blue whortleberry (Vaccinium myrtillus); berry of this shrub”); further etymology unknown, compare Middle English horten, hurten (“bilberry (Vaccinium myrtillus)”), and Old English horte (“bilberry (Vaccinium myrtillus)”).
