The author studies the codification principles of Henrich Bartek formulated in his design of the Slovak orthographic rules from 1939, their continuity with codification in 1953 and the difference between the etymological and phonetic criterions in the conception. Special attention is paid to the functionality of Bartek's codification principles, to the dominance of the phonetic criterion and to some inconsistencies in the codification layout from 1939 due to uneven attitude to graphical and acoustic form.
