firmament

The firmament (sense 1) or sky.

One version of the Ptolemaic system of celestial spheres, with the firmament (indicated in Latin as Firmamentu; sense 3) shown as the eighth heaven^{[n 1]}

From Middle English firmament, furmament (“heaven; sky”),^[1] from Old French firmament (“firmament”), or from its etymon Latin firmāmentum (“support; sky”), from firmāre (“to strengthen”) + -mentum (suffix indicating an instrument or medium, or the result of an action). Firmāre is the present active infinitive of firmō (“to make firm, strengthen”), from firmus (“firm, strong, stable”), ultimately from Proto-Indo-European *dʰer- (“to hold; to support”).^[2]

The Latin word was used in the Vulgate version of the Bible to translate the Ancient Greek στερέωμα (steréōma, “foundation, framework; firmament”) in the Septuagint (Greek Old Testament), which in turn was used to translate the Hebrew רָקִיעַ (rāqī́aʿ, “celestial dome, vault of heaven”), from the root ר־ק־ע (r-q-`); in Classical Syriac the similar root ܪ ܩ ܥ (related to compacting) gave rise to ܪܩܝܥܐ (rəqīʿā, “compact; firm; firmament, heavens, sky; celestial sphere”).^[2]
