I am wondering whether a barking dog means the same as a dog which is barking.
Here is the saying a barking dog does not bite. Does a barking dog herein mean a dog which tends to bark in face of threat or a dog which is barking?
Similarly, could I saw a patient coughing be rephrased as I saw a coughing patient?
Besides, does a waiting car refers to a car that is arranged a priori to pick sb. up or a car that happens to be seen waiting, say for passengers getting in or for a traffic light turning green?
Also, sleeping as an adjective collocates with child, as in this ODE example a sleeping child; could one likewise say a sleeping student/lady/man/etc.?
Thanks in advance!
