Have a good day!, you type, but that’s what everyone else says, and there’s got to be something better.
So you turn to the thesaurus. Have could be own, keep, maintain, utilize, occupy. Good, in turn, could be fine, quality, superb, exceptional, sterling, first-rate, and so on. Day could be twenty-four hours, but it’s also used as a stand-in for period, era, age.
Rely on a thesaurus alone, and you could end up with Occupy a first-rate era! or Maintain a fine age as your salutation. An insight, perhaps, into how automated translation can go so wrong, but hardly a helpful way to improve your emails.
Yet the idea’s still solid. You don’t want to repeat yourself. Your sentence length can vary enough to let your words sing, only to lose the effect with subpar words. You can only talk about good things so many times before your readers’ eyes glaze over.
