ἀκτίς

Etymology
From an source apparently shared with 🇨🇬, perhaps: The suffix is unexplained in any case.
 * , from an unidentified root;
 * , which would exclude the Sanskrit;
 * ,, from , with an obscure semantic development, perhaps “end of the night” which shifted to “dawn”, as paralleled by 🇨🇬, and then “first light of dawn; ray of (dawn sun)light”. This is evidenced by the night-related meanings in the Sanskrit cognate. However, Beekes rejects this etymology due to the lack of evidence for a labiovelar.
