solus

Borrowed from Latin sōlus.

solus (not comparable)

1. alone, unaccompanied (as a stage direction)

   Enter Hector solus.

• souls

• Often derived from earlier *swolos, from Proto-Italic *swelos, from Proto-Indo-European *swé (reflexive pronoun) (whence se (“oneself”)) + *-los, hence meaning "by oneself";
• De Vaan refers it to *solh₂- (“whole, healthy”), which would make it akin to sollus and salvus.
• Others connect it with Proto-Germanic *sēliz (Gothic 𐍃𐌴𐌻𐍃 (sēls, “happy, good”), Old English sēlra (“better”)), from Proto-Indo-European *selh₂- (whence sōlor (“to console”)).

• (Classical Latin) IPA^(key): [ˈsoː.ɫʊs]
• (modern Italianate Ecclesiastical) IPA^(key): [ˈsɔː.lus]

sōlus (feminine sōla, neuter sōlum); first/second-declension adjective (pronominal declension)

1. alone, sole, only, by oneself with no others around

   Sentīs mea vulnera, sentīs; atque utinam sōlī sint ea nōta tibi.

   You feel my wounds, you feel: and I hope they are only known to you.

   • 29 BCE – 19 BCE, Vergilius, Aeneis 4.22-23:

     “[...] sōlus hic īnflexit sēnsūs, animumque labantem / impulit [...].”

     “[...] this [is the] only [man who] swayed [my] feelings, and stirred [my] wavering heart [...].”

2. solitary, uninhabited
   • 8 CE, Ovidius, Fasti 4.513–514:

     ‘māter!’ ait virgō (mōta est dea nōmine mātris)
     ‘quid facis in sōlīs incomitāta locīs?’

     ‘‘Mother!’’ says the maiden (the goddess was moved by the name of mother),
     ‘‘What are you doing unattended in lonely places?’’
     (A young shepherdess chances upon the goddess Ceres who, having disguised herself as an old woman, is searching everywhere for her own lost daughter, Persephone.)

First/second-declension adjective (pronominal declension).
