Tocharian B word "āk" had a meaning of "ear of grain". The word for "ear of grain" in Russian is "ость" (ost'), which is the same as Polish "ość" which denotes a "fishbone".
The shape of "ear of grain" truly resembles that of a "fishbone".
Latin "arista" (?asista) means exactly "awn" (beard of grain) and "ear of grain".
Latin "agna" means "ear of wheat", Lithuanian "ašnìs" is "edge, blade", Czech "osina" is "awn", Ancient Greek "ἄκαινα (ákaina)" is "spike, prick" and "ἄκανος (ákanos)" is "pine-thistle", Sanskrit "अशनि (aśáni)" is "thunderbolt, arrow tip".
All of those words direct us to the root of the Indo-European word for "bone" taken from something like "blade or a sharp object" or in general something that looks like "ear of grain".
Lithuanian "akuotas" is the best proof of this theory because it means: "awn, barb, BEARD and fishbone".
Basque word for bone "hezur" might also be related and would come from the language of Early European Farmers (AHG + WHG) or Bell Beaker Culture (Y-DNA R1b Indo-European) as opposed to Germanic "bone" from pure WHG (Y-DNA I1).
