History for yolk
The word yolk goes back to Old English geoloca (a spelling that seems less strange when you know that ge- in Old English could stand for the sound /y/). Geoloca, in turn, is a derivative of geolu, the ancestor of our word yellow. This makes perfect sense given the color of a yolk, but changes in pronunciation over the course of centuries no longer make the relationship of the words obvious.
