Sampson (1985) suggests that: "Evidently the order of the alphabet was felt to be such a concrete thing that a new letter could be added in the middle only if a 'space' was created by the dropping of an old letter."
Sampson (1985) berpendapat bahwa: "Jelas sekali bahwa susunan alfabet dirasakan sebagai perihal yang begitu konkrit sehingga suatu huruf baru boleh ditambah di tengah susunan hanya jika terdapat 'ruangan' setelah menggeser huruf yang lama."
