Which words most likely means a condition in which a person has elevated levels of glucose in the bloodstream?
The name is certainly from an Old Germanic root, but it is not clear which of several similar-sounding words gave rise to the name. Most likely is lint, which means "soft" or "tender". Also plausible is lind, which means a "linden tree". Less likely but still possible is the lind that means "serpent".
