doll: [16] Doll comes from the name Dorothy: the changing of r to l in personal names is a common English phenomenon of long standing, from Shakespeare’s Prince Hal (for Harry) to the currently familiar Del and Tel (for Derek and Terry). The word was originally applied to a man’s mistress (much like moll, which came from Mary), but in the 18th century it came to be applied to a ‘toy baby’. The pet form dolly dates from the 17th century.

sally: [16] To sally is etymologically to ‘jump’. For the word comes ultimately from Latin salīre ‘jump’, source also of English assail, insult, salient, etc. It passed into Old French as salir, which later became saillir. From this was derived a noun saillie ‘jump’, hence ‘sudden breaking out from a defended position to attack’, which English took over and soon turned into a verb. (The name Sally, incidentally, is an alteration of Sarah, by the same phonetic process that produced Del, Hal, Moll, and Tel from Derek, Harry, Mary, and Terence.)
