lodestar (English)

Where does "lodestar" come from?

The English noun 'lodestar' is a compound formed in Middle English from 'lode', meaning 'journey, course', and 'star'[1]. The first element 'lode' continues the old sense of Old English 'lād', meaning 'way, course, journey'[3], which descends from Proto-Germanic '*laidō'[4]. The second element 'star' descends through Middle English 'sterre' and Old English 'steorra'[2][8] from Proto-Germanic '*sternǭ'[2][9], which ultimately traces back to the Proto-Indo-European root '*h₂stḗr'[2][9], meaning 'glower, shiner'[6]. Cognates across Germanic languages include Old Norse 'leiðarstjarna', Dutch 'leidster', and German 'Leitstern'.

Open questions

The Proto-Indo-European root for star is derived from a base meaning to burn or glow, though the morphological breakdown into an agentive suffix is a reconstruction. [6]
The Germanic n-stem variant with an assimilated r sound is explained by Kluge's law, while forms showing an n are considered reintroductions. [9]
