Pronunciation

  • Classical: [soː.lɪˈtuː.doː][1]
  • Ecclesiastical: [so.liˈtuː.do][1]

Forms

sōlitūdō f (genitive sōlitūdinis); third declension[1]

Etymology

It is formed from Latin sōlus (“alone”) + -tūdō.[2][1][3] The origin of sōlus is uncertain: de Vaan rejects the link with the reflexive ⟨*s(w)e⟩ “apart” that Walde and Hofmann, Pokorny and Ernout and Meillet proposed, and mentions a Gothic adjective for “happy” and the root of salvus and sollus (“whole”) as possibilities.[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[4] who uses it for being without friends: sōlitūdine ego tēd atque ab egestāte apstulī, “I took you away from loneliness and want”.[2] Terence has it for being alone with someone.[2]

Semantic evolution

Sōlitūdō is the state of being alone, solitude, and the state of having no friends or protectors, loneliness, forlornness (Plautus).[2][5] Of places it is emptiness, the deserted state of a place (Terence: sōlitūdō ante ōstium, “nobody at the door”), and then a deserted region, a desert or wilderness, usually in the plural (Cicero: saxa atque sōlitūdinēs vōcī respondent).[2][5][1] It also means want, destitution.[1]

Döderlein says that sōlitūdō is the solitude of a place, neutral or praised, while vāsta, dēserta and tesca loca are words of blame.[6] Church Latin glosses it “solitude, loneliness, wilderness”.[7] English solitude (mid-14th century) comes from it, partly through Old French.[3]
