Wary and Weary is another pair that seems to be giving the writer baes trouble. Here's a little help for you to make sure you get it right so your readers won't have to figure it out.
Wary
"Wary" describes the feeling or state of being watchful, cautious, on guard, or suspicious against potential danger or trouble. Someone may be wary of strangers or new situations, potential mates who sound too good to be true or too many trolls congregating in one area, dark alleys or men standing oddly still while wearing masks.
Weary
"Weary" describes the feeling or state of being physically or mentally exhausted or tired of something to the point of impatience, aggravation, or boredom. Someone may be weary after a long day of work, or as Otis Redding sang, "Oh, she may be weary; And them young girls, they do get weary; Wearing that same old shaggy dress."
"Wary" and "weary" are two completely different words, and one does not capture the meaning of the other. These words are not interchangeable and should not be used as synonyms. Like most adjectives, it's possible to be both wary and weary at the same time; however, being one does not mean someone is both.
And there you have it, folks! Wary vs. Weary. Use responsibly!
