From Proto-Hellenic *artús, from Proto-Indo-European *h₂(e)r-tús (“form, order; bond”), from the root *h₂er- (“to fit together, join”).
Cognates include Latin artus (“joint, sinew, limb; power”), Old Armenian արդ (ard, “shape, order”), Sanskrit ऋतु (ṛtú, “union; order, rule; time period”), Avestan 𐬭𐬀𐬙𐬎 (ratu, “time period”) and Middle Persian (lt' /rad/, “master; judge”).
Apparently semantically merged in prehistory with ἀρθμός (arthmós), despite the different suffix.
ἀρτύς • (artús) f (genitive ἀρτύος); third declension
