How to Speak and Write Correctly

by Joseph Devlin

AND WITH THE RELATIVE

Never use and with the relative in this manner: "That is the dog I meant and which I know is of pure breed." This is an error quite common. The use of and is permissible when there is a parallel relative in the preceding sentence or clause. Thus: "There is the dog which I meant and.which I know is of pure breed" is quite correct.
