Abstract: An electronic dictionary or language translator is in the form of a thin electronic device, preferably at least 3".times.6" in size so that it may be placed in a book and used during reading. The electronic device has a relatively large display area and its keys are spread apart so that they may be readily operated by the fingers of either hand. The device utilizes a specially arranged keyboard with an alphabetical sequence of the letters, but with the vowels positioned so that they start and end each row. In addition, certain vowels are repeated both on the left and right sides of the keyboard.
