Etymology: The word "titty" is built from "tit" plus the diminutive suffix "-y", which turns a noun into a pet or familiar form. Its first ingredient, "tit", is an old word for a small bird (the tit family, such as the great tit), and the bird name itself is related to ideas of smallness and something little or quick. Adding "-y" gave a childish, affectionate diminutive, and the same pattern produced words like "doggy" and "kitty". The sense of "sister" is more surprising and less settled. It is perhaps a baby-talk form of "sissy", itself a diminutive of "sister", so the word drifted from a familial nickname into a slang term for a sibling. Because the source offers this only as a possibility, it is best read as a plausible explanation rather than a firm one.
