ARKTOS
Arktos is Ancient Greek for a "bear". It is also related to an English word "Arctic", which derives from Ancient Greek "ἄρκτος (árktos)" meaning "having to do with the Great Bear (Ursa Major)" or "Northern lands (lands near Ursa Major)". That is why for an icon for this article I chose a polar bear.
The star name "Arcturus" means "guardian of the bear". The Celtic name "Arthur" means "Bear-like".
The name of a bear in Lithuanian is "lokys", "lacis" in Latvian, and "clokis" in Old Prussian, all those words mean "hairy, shaggy" and refer to the texture of bear's coat. In Polish that word is "kłaki" meaning "uncombed hair".
Old Church Slavonic name "медвѣдь (medvědĭ)" and all other Slavic names are showing the connection of a bear with honey. Polabian Drevani "graswuy" name for a bear could come from the verb "grasowat" meaning "to plunder".
Bulgarian "ме́чка (méčka)" and Serbo-Croatian "ме̏чка, mȅčka" is very similar to Lithuanian "meška", not only that but non Indo-European languages of Caucasus mountains like Abaza "мшвы́ (mš°ə́)", Adyghe "мышъэ (məŝă)" and Kabardian "мыщэ (məŝă)" show the same similarity of a word for a bear. Itelmen language of Kamchatka Peninsula "массу (massu)", Native American Munsee "mahkw", Unami "màhkw", Massachusett "mosq", Montagnais "mashkᵘ", Eastern Mari "маска (maska)", Western Mari "мӧскӓ (möskä)", Udihe "мафа (mafa)" and finally Russian "ми́шка (míška)" but this single language could not influence all those other languages and there is also Polish "miś". The origin of this word must lay in Eastern Hunter Gatherer or rather Ancient North Eurasian tribes that contributed to the Yamnaya DNA. This theory would make "meska" or "misa" the most certain original "Indo-European" word for a bear without any taboo behind it.
