The problem of delimiting the intermediate status of the scientific Greek-Latin elements has been discussed by derivatologists for a long time. In linguistics, this problem has engendered a num-ber of controversies: some scholars consider the scientific Greek-Latin elements as affixes and thus as derivatives; others – as constituent parts of the compound words; the third category of researchers recognizes their intermediate character. The affixoids result from a successful combination of nomi-nal and structural (linguistic) characteristics. The affixoidation, a sub-process of compounding, is based, in general, on the revitalized Latin-Greek model of compounding.
