[IND] The paper discusses some changes of a and e, as observed in Turkish loanwords in Macedonian, which enables us to see how important these words are also for Turkish historical dialectology. In the final part of the study, a lexicographical suggestion is made: What we really need is a comparative (and, if possible, a historical) dictionary of Turkish loanwords in the Macedonian language area. Without it, we will never be in a position to establish their precise etyma.
