spurium

• (Classical) IPA^(key): /ˈspu.ri.um/, [ˈs̠pʊriʊ̃ˑ]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈspu.ri.um/, [ˈspuːrium]

Unclear, perhaps from a derivation of Ancient Greek σπορά (sporá, “seed”) like σποραῖον (sporaîon), but transmitted by Plutarch’s Questions 103 as Sabine, thus guessed from Etruscan, and perhaps natively related to spurcus (“foul”) of a suffix like murcus and to spurius (“bastard”).

spurium n (genitive spuriī or spurī); second declension (Late Latin, rare)

1. pudendum muliebre
2. a marine animal of similar shape

Second-declension noun (neuter).
