"I...became convinced that anything up to a quarter of the Greek vocabulary could be traced to Semitic origins. This, together with 40–50 per cent that seem to be Indo-European, still left a quarter to a third of the Greek vocabulary unexplained. I hesitated between seeing this irreducible fraction conventionally as ‘Pre-Hellenic’ or of postulating a third outside language, either from Anatolian or—as I preferred—Hurrian. When I looked into these languages, however, they provided virtually no promising material. It was only in 1979, when I was glancing through a copy of Černy’s Coptic Etymological Dictionary, that I was able to get some sense of Late Ancient Egyptian. Almost immediately, I realized that this was the third outside language. Within a few months I became convinced that one could find plausible etymologies for a further 20–25 per cent of the Greek vocabulary from Egyptian, as well as the names for most Greek gods and many place names. Putting the Indo-European, Semitic and Egyptian roots together, I now believed that—with further research—one could provide plausible explanations for 80–90 per cent of the Greek vocabulary, which is as high a proportion as one can hope for in any language. Thus there was now no need for the ‘Pre-Hellenic’ element at all."
