Abstract
Abstract An electronically operated machine for learning foreign language vocabulary constructed with a plurality of bits for storing in each of them character informations constituting words; a memory device consisting of a bit to store in it a character determining information indicating whether the words stored in the plurality of bits are to be represented by the capital letter, or not; a retrieving and call-out device to call out the words stored in the memory device; and a discriminating device to determine, by the capital letter determining information stored in the determining bit for the word as called out by the retrieval and call-out device, whether the initial letter of the work starts with the capital, or not.
