In the 19th century, there was a debate about the spelling of this, which

Tom Dalzell might find useful. This is from the Richmond (VA) Dispatch, 26

September 1874, pg. 2, col. 3:

The word _whisky_ has no _e_ in it, and its plural is _whiskies_, not

_whiskeys_.--_Petersburg Index (selected)_.

Yes it has; and its plural is "_whiskeys_." (See WORCESTER.) It comes

from "_usquebaugh_."
