On the Nawatl Scholar blog, I published an analysis of the two main interpretations of the Aztec writing system. Aztec writing combined logograms (word signs that can be read in any language) with phonetic signs (that spell a specific language), but scholars are discussing whether the phonetic signs were strictly syllabic or whether they could be more complex. I weigh in with my own evaluation of the strengths and weaknesses of the two interpretations.
