There is something about her

There is something about her

Coincidence? Trying to figure out what it means when they say, "There's something about Mary?" Often this phrase, "There is something about him/her," is followed by, "but I can't quite put my finger on it." What there is about him or her is typically not known or stated, since the speaker can't quite put his finger on what it is. When there is a second clause it might be, "that I don't like," or "that makes me want to know her better," or "that doesn't seem quite right," or "that doesn't smell good," or "that makes me suspicious" or "that makes my heart beat faster." The "something" that there is about so-and-so can be good, bad or, rarely, indifferent. SS
