Etymology
It is inherited from Proto-Hellenic *hágiyos, inherited from Proto-Indo-European *h₁yáǵ-yo-s, from *h₁yaǵ- (“to sacrifice, worship”).[1] Beekes accepts the comparison with Sanskrit यजति (yájati, “honours with sacrifice and prayer”), which he finds unobjectionable in meaning; by Lubotsky's rule the root can be set up as Proto-Indo-European *Hieh₂ǵ-, whose glottal element was lost before a consonant, so that an /a/ vowel need not be assumed for the root, as the LIV and others do.[2][3] He takes ἅγιος as the primary noun with the suffix *-iHo-.[2]
The same root, with another suffix, is in ἁγνός (hagnós, “pure, chaste”), and in ἅζομαι (házomai, “to stand in awe of”).[2][4][5]
Earliest recorded meaning
BDAG cites a fragment of the tragedian Thespis that speaks of holy altars; otherwise the word is found from the 5th century BC as a cultic term in Ionic and Attic.[6] Herodotus calls a sanctuary of Aphrodite and one of Heracles ἅγιον, “holy”.[3][5]
Semantic evolution
In Classical Greek it describes places, rites and objects that belong to the gods: temples, sacrifices, oaths, and the mysteries.[3][6] It is rare in Attic and is never used by Homer, Hesiod or the tragedians, who say ἁγνός (hagnós) instead.[3] Plato calls one's fatherland more hallowed than one's mother, and Aristophanes uses it of birds treated as gods.[3][4] Cratinus has it once in a bad sense, “accursed”.[3]
In the Septuagint Israel is a people holy to the Lord, and τὸ ἅγιον is the sanctuary, τὸ ἅγιον τῶν ἁγίων the Holy of Holies.[3][6] In the New Testament it is used of God, of the Holy Spirit (πνεῦμα ἅγιον) and, as a noun, of Christians, “the saints”.[3][4][6]
In post-classical and medieval Greek ἅγιος was also a noun for a saint.[7][8] It continues as Modern Greek άγιος (ágios), with synizesis to avoid the hiatus, in the senses “saint” and “holy”, and as a learned word in the old sense “sacred”.[9][5] The English prefix hagio- comes from it.[8]

Usage notes
In Classical Greek ἁγνός (hagnós), not ἅγιος, is the poetic word: LSJ notes that ἅγιος is never found in Homer, Hesiod or tragedy and is rare in Attic.[3] BDAG explains it as the quality of things and persons that may approach a divinity.[6]
