salmon & salmonella
you can catch both salmon and salmonella, you can eat an improperly prepared dish of the former and get unexpectedly poisoned with the latter, and of course, you can’t spell salmonella without first spelling salmon. yet, these words do not share any etymological roots.
salmon is from the latin word, salmonem (salmon) and possibly salire (to leap.) salmonella is named after daniel elmer salmon, a veterinary researcher. his odd surnameis an old french corruption of shalom, the hebrew word for peace.
