For all his psychological hang-ups, Tyler Durden had it right when he said, “You are not a beautiful or unique snowflake.”
There were no ifs or buts about it. He didn’t call us less unique; he didn’t wish we were more unique. No, Tyler Durden must have known that the word “unique” was not meant to be used with indecision.
As any grammar enthusiast will know, the word “unique” means “one of a kind.” People or objects cannot be more or less unique, they either are or they are not. If you want to indicate that something is uncommon or different, you’d be better off using “unusual” instead.
