Write a novel, screenplay or play and use deadwood phrases in dialog. Dialog is the one place where anything goes in literature. When people speak, they don't always use proper grammar. Many people use double negatives and deadwood phrases such as in order to, a majority of, basically, essentially and totally. All of those are deadwood phrases, but find themselves in the conversations and dialog of many people.
Use deadwood phrases if the other form has been used several times already and you don't want to sound repetitive. For example, "a majority of" can easily be changed to "most" and "ascertain the location of" can be changed to "found". If while writing you have already used the shorter phrase several times and you don't want it to be peppered with the same phrases over again, then you can substitute the deadwood phrase occasionally.
Choose to use a deadwood phrase in your writing. While deadwood phrases are not suggested to use for technical and journalism writing, there is nothing illegal about them. If you want to write in a conversational tone and the natural flow of the writing includes deadwood phrases, then feel free to use them. This is especially true if the writing is for personal use.
