Root / Etymology

From the preposition κατά ('down, according to') and χθών ('earth, ground'), with the suffix -ιος forming an adjective. Thus, 'of or pertaining to under (the) earth.'

Historical & Contextual Notes

In classical Greek, καταχθόνιος was used for gods, spirits, or entities connected to the underworld or beneath the earth, such as the chthonic deities, contrasting with οὐράνιος (ouranios, 'heavenly') or ἐπιχθόνιος ('upon the earth'). In Hellenistic and Roman-period literature (including the New Testament, e.g., Philippians 2:10), the term designates that which is 'under the earth', widening its referent to all that inhabit the underworld or realm of the dead. The Septuagint does not use the term, but parallels exist in Greco-Roman religious language. Traditional English translations often render it as 'under the earth' or 'infernal', which may reflect influence from classical Greek conceptions of the cosmos. The nuance of 'subterranean' can be broader than merely 'belonging to the world of departed spirits', retaining physical and mythological dimensions.

Original Strong's Gloss (1890)

from κατά and (the ground); subterranean, i.e. infernal (belonging to the world of departed spirits):--under the earth.
