If you're wondering what it means when someone says he or she's "smitten" with someone, here is the applicable smitten definition: "being loving, amatory, amorous, or fond." The smitten definition can go even further, though, depending upon the context of the statement: "marked by foolish or unreasoning fondness." The word "smitten" is derived from the verb "to smite," which means, in simplest terms, to hit. When someone is smitten in love, he is either literally or figuratively "hit" by love.
The term smitten can have positive connotations or negative. The first smitten definition referenced in this article merely has the word meaning someone being in love or having loving feelings toward someone or something. A guy who's smitten with a woman might go out of his way to send her flowers or do other nice things to show how much he cares. The second smitten definition, however, is slightly more sinister, especially if the other person does not feel the same way. While some might say someone who's smitten is completely and totally in love, someone else might use the same word to say that someone is obsessed.
The smitten definition, like that of many words, depends upon the context. When someone says that two people who are getting married are smitten with one another, it's obviously a good thing, a sure sign that they are right for each other. If someone declares him or herself smitten with someone who does not feel the same way, though, it can mean something entirely different. Be sure when encountering the word to gather clues as to the right smitten definition; it's a versatile word and its meaning and, when determined properly, can save a lot of heartache.
