Abstrakt
Based on archaeological and philological considerations, it seems plausible to identify in the first element of Gk ἄμπυξ 'frontlet' the PIE root-noun *h2énts This implies the PIE lexeme was continued in Pre-Greek in the primary meaning 'forehead' This in turn provides another argument against accepting that the same lexeme could have meant 'side' in PIE and could have engendered terms such as PIE
*h2mbhí 'around/on both sides' and *h2mbhóh1 'both' which crucially depend on such general semantics (as claimed by Jasanoff 1976)
Typological, semantic, and philological arguments make it possible to conclude that PIE *h2énts had the very simple primary meaning
'forehead', all the later derivation can be based on this meaning, and invocation of a more general noun 'front' or 'surface' is unnecessary and superfluous
