Palatium

Of uncertain origin. Either from:

• Etruscan 𐌚𐌀𐌋𐌀𐌃 (falad, “sky”), the same source as Palēs (“Pales, the Italic goddess of shepherds, flocks and livestock”);
• palātum (“roof of the mouth; dome, vault”), itself perhaps related to the Etruscan term above;[1]
• pālus (“stake; enclosure”).

Palātium n sg (genitive Palātiī or Palātī); second declension

1. One of the seven hills of Rome.

Second-declension noun (neuter), with locative, singular only.

¹Found in older Latin (until the Augustan Age).
