+ ==Pronunciation==
+ * Classical: [pɛrˈɫʊ.kɪ.dʊs]^(Wiktionary)
+ * Ecclesiastical: [perˈluː.t͡ʃi.dus]^(Wiktionary)
+
+ ==Forms==
+ '''perlucidus''' (feminine perlucida, neuter perlucidum); first/second-declension adjective^(Wiktionary)
+ It is also spelled ''pellūcidus''.^(OLD 2012)^(TLL)
+
+ ==Etymology==
+ It is [[af|la|perlūceō|-idus|t1=to shine through]], as the OLD has it; the TLL takes it as ⟨per-⟩ added to [[m|la|lūcidus|t=bright]].^(OLD 2012)^(TLL) Both go back to the family of [[m|la|lūx|t=light]], which de Vaan traces to [[ine-pro|*leuk-|t=light]], cognate with [[grc|λευκός|tr=leukós|t=clear, white]].^(de Vaan 2008)
+
+ ==Earliest recorded meaning==
+ Plautus has it in the ''Persa'', of a clear broth, with the spelling ''pellūcidus'';^(OLD 2012)^(TLL) the TLL finds that spelling only there.^(TLL)
+
+ ==Semantic evolution==
+ It means transparent, letting light through,^(OLD 2012)^(Wiktionary) and figuratively clear in meaning, as Vitruvius says of plain thoughts and sentences.^(OLD 2012) It also means very bright, radiant: Cicero contrasts a dim star with a bright, clear one in the ''De divinatione''.^(OLD 2012) Döderlein separates the two senses by spelling, ''perlūcidus'' “very bright” and ''pellūcidus'' “transparent”.^(Döderlein 1874) The comparative is found from Cicero and Horace, the superlative only in Hilary.^(TLL) Stelten glosses it “transparent”.^(Stelten 1995)
