+ '''idōneus''' (feminine idōnea, neuter idōneum, comparative magis idōneus, superlative maximē idōneus, adverb idōneē); first/second-declension adjective^(Wiktionary)
+ The jurists in the Digest have the comparatives ''idōneior'' and ''idōnior''.^(OLD 2012)
+
+ ==Etymology==
+ The origin is unknown.^(de Vaan 2008)^(OLD 2012)^(TLL)^(Köbler 2010) De Vaan notes that it could be an adjective in ⟨-neus⟩ from an adverb ⟨*idō⟩ “there” or a stem ⟨*ido-⟩, or one in ⟨-eus⟩ from ⟨*idōn⟩, but that neither leads to a likely etymology.^(de Vaan 2008) Wiktionary reports Brugmann's derivation from an unattested adverb ⟨*idō⟩, as [[m|la|ultrōneus]] is from [[m|la|ultrō]] and [[m|la|extrāneus]] from [[m|la|extrā]].^(Wiktionary) Lewis & Short linked it with a Sanskrit root “to kindle”, “bright, conspicuous”.^(Lewis & Short 1879)
+
+ ==Earliest recorded meaning==
+ De Vaan and Köbler date it from Plautus.^(de Vaan 2008)^(Köbler 2010) Terence has ''nequeō … initium ūllum invenīre idōneum unde exōrdiar'', “I can't find any suitable point to start from”.^(OLD 2012)
+
+ ==Semantic evolution==
+ ''Idōneus'' is “having the right qualities, suitable, fit, adequate”, of persons and things.^(OLD 2012)^(Lewis & Short 1879) In law it means “solvent, able to meet one's obligations”, of a debtor or a guarantor.^(OLD 2012) Döderlein says it denotes a passive fitness, made fit by qualities or circumstances, and ''[[aptus]]'' an active one.^(Döderlein 1874)
+
+ Church Latin glosses it “suitable, sufficient, proper”.^(Stelten 1995) Medieval Latin uses it of an accused man cleared of a charge, of a trustworthy witness, and of a person able to go to law.^(Niermeyer 1976)
+
+ ==Timeline==
+ * c. 250–184 BC – Plautus uses it.^(de Vaan 2008)^(Köbler 2010)
+ * 190–159 BC – Terence: ''initium … idōneum''.^(OLD 2012)^(Köbler 2010)
