This terrific mixed idiom was heard on Marc Maron’s WTF podcast. Musician Jimmy Vivino was discussing his development in learning to arrange music and mentioned a book on orchestration that a teacher had given him that he read in its entirety. This is a combination of “front to back” and “cover to cover”, both meaning to have read something in its entirety. There is also a British expression, knowing “(something) back to front”, which also means to know something completely or in its entirety. How many of you have literally read a book front to cover, and decided that was enough? Liner covers do serve a useful purpose. A big thank you to Mike Kovacs, who listens and reads front to cover for malaphors.
