put (lay) one’s finger upon. Sherlock Holmes seems to be the first person to have used to lay one’s finger upon, “to indicate with precision,” in Sir Arthur Conan Doyle’s The Memoirs of Sherlock Holmes (1895): “You lay your finger upon the one point . . .” But a little sleuthing reveals that the expression had been used at least five years earlier as to put one’s finger upon, in reference to a physician (not Dr. Watson) discovering the cause of an illness. |
