The aim of the paper is to suggest a number of new etymologies as well as to review some old comparisons in I.E. The practice of ignoring the centum evidence for the voiceless labiovelar aspirates is common in the modern Indo-European lexicography and etymology. Greek is the only language which preserves the voiceless aspirates and contains some traces of labiovelars. This is why the author discusses the problem once more. The author suggests a number of new etymologies and comparisons in IE based on Greek evidence. The lexical material discussed in the paper allows to reconstruct the voiceless labiovelar aspirate in the late period of existing of IE language.
