arborvirus, arbovirus

What's in a name? Although arbor sounds as if it should have something to do with trees, it doesn't. It comes from the first two letters of arthropod + the first three letters of borne. Arborviruses are transmitted (borne) to humans by mosquitoes and ticks (arthropods).

Since the name Arborvirus proved too clever by far; the spelling had to be replaced by Arbovirus, dropping the second "r" because of the potential of misidentification with trees. The first two letters of each word, arthropod' and borne, became the arbo that now associates this category of viruses with arthropods.

Motto of the University of Toronto, Toronto, Ontario, Canada.

From the University of Toronto's Web site: "The form of the crest as it exists today, was adopted by the University of Toronto in 1917 when the Board of Governors of the University, on account of the many incorrect forms in common use, applied to the College of Heralds for a correct emblazoning of the Arms of the University of Toronto and of University College.

The motto velut arbor aevo is generally translated "As a tree in the passage of time" in the University's motto.
