akmens

 akmens on Latvian Wikipedia

From Proto-Balto-Slavic *ákmō, from Proto-Indo-European *h₂éḱ-mō (whence also asmens, originally a parallel form to akmens, created by a different development of *ḱ, perhaps due to Proto-Indo-European dialectal differences), from the stem *h₂éḱ- (“sharp, pointy, angular; stone”) with an extra element -men. Cognates include Lithuanian akmuõ, genitive akmeñs, Sudovian akmi, Hittite (aku, “sharp stone”), Sanskrit अश्मन् (aśman, “stone, rock, sky”), Avestan 𐬀𐬯𐬨𐬀𐬥 (asman, “stone, sky”), Ancient Greek ἄκμων (ákmōn, “anvil”), ἀκμή (akmḗ, “spike, edge, blade”); with reduction (zero grade) of the stem (*h₂éḱ-h₂-men > Proto-Slavic *kamy (“stone”)), also Belarusian, Russian ка́мень (kámenʹ), Ukrainian ка́мінь (káminʹ), Bulgarian ка́мен (kámen), Czech kámen, Polish kamień.^[1]

According to more recent analyses, the corresponding form may have been *ákmō all the way up to Eastern Baltic unity, thus identical to the Proto-Balto-Slavic form.
