What Do You Call Two BlackBerry Phones?
Sara from Harrisburg, PA, writes, "My friend asks an interesting question:
In plural form, is it BlackBerrys or BlackBerries."
Although we typically make words that end in "y" plural by replacing the
"y" with "ies," the same rule does not hold true for family names. For example,
it is generally agreed that the plural of "Kennedy" is "Kennedys."
If your gadgets were more like fruit, then we would call two of them
"BlackBerries." But I believe a brand name is more like a family name, and
therefore, the proper plural is "BlackBerrys." A search of the BlackBerry website
also shows that the company agrees and uses the plural "BlackBerrys."
