Etymology
Beekes and Frisk take it as the adjective from Ancient Greek θεμέλια (themélia, “foundations”), “belonging to the foundations”, used as a noun for the foundation stone.[2][3] Homer has the plural only in the metrically lengthened form θεμείλια (themeília), beside θέμεθλα (thémethla) of the same meaning.[2][3] Both are formations with the suffixes -λο- (-lo-) and -θλο- (-thlo-) from a nominal stem in ⟨-μ-⟩, seen in Hesychius' θεμούς (themoús), and go back to the root of τίθημι (títhēmi, “to put”), Proto-Indo-European *dʰeh₁- (“to put, set”).[2][3][4] Wiktionary reconstructs *dʰh₁-m-eló-.[1]
Earliest recorded meaning
Aristophanes' Birds (5th century BC) speaks of foundation stones, and Thucydides uses the masculine plural for the foundations of the walls of Athens, laid with stones of every kind.[5][6][4]
Semantic evolution
Aristotle uses the masculine for a foundation stone, and the neuter θεμέλιον, mostly in the plural, appears beside it from the 3rd century BC.[5] The phrase “from the foundations” meant completely, of a house burnt or of people utterly mistaken or ruined.[5] Figuratively it was the foundation of an art or of ignorance, and Epicurus calls the first principles the foundations of the world.[5]
In the Septuagint and the New Testament it is the foundation of a building and of the heavenly city, and Paul calls Christ the only foundation that can be laid.[6] Medieval Greek kept the noun, as Cypriot does today.[7] Modern Greek has the learned adjective θεμέλιος (themélios) “fundamental”, and the noun θεμέλιο (themélio), mostly in the plural, “foundations”.[8][4]
