This paper argues that the segment /j/ in Hungarian is neither a fricative (as traditionally claimed) nor a glide (as it is usually classified in the international literature). The arguments adduced involve syllabification patterns, processes of j-obstruentisation, phonetic details of hiatus resolution, as well as phonotactic phenomena. Additional problems that are touched upon include the question whether Hungarian has diphthongs, the behaviour of /j/ with respect to vowel zero alternation, voicing assimilation and final devoicing, the analysis of imperative forms of t-final verbs, as well as the relationship between the Duke of York gambit and the principle of Proper Inclusion Precedence
