Only, Alone.—“He alone can do it,” implies that he can do it without help. It would be better, “He can do it alone.” “He only can do it,” signifies that he, and no other person, can do it. Using alone in the sense of only may lead to ambiguity.
Onto.—We get on a horse and on a chair, not onto.
Orate.—An unauthorized form commonly used to mean to give an oration.
Over.—Do not use over in the sense of more than; as, “I have over a hundred dollars”; “The stick is over a yard long.”
Over a bridge.—“He went over the bridge.” It is more exact to say, “he went across the bridge.” A bird may fly over a bridge, if it does not touch the bridge.
