Use the adjective nary to mean "none," or "not a single one." If you hope for a snowy morning, when you wake up you'll be sad to see nary a snowflake.
Nary is an old fashioned and informal way to say "not." You might describe your friend's sad, empty book shelves with nary a novel on them, or your bald great uncle, who has nary a hair on his head. The word has been around since the mid-1700s, from never a, which was then shortened to ne'er a, and finally nary.
