fortīs Fortūna adiuvat

1. fortune favors the bold
   • 161 BCE, Publius Terentius Afer, Phormio 203:

     Ergo istaec quom ita sint, Antipho,
     Tanto magis te advigilare aequomst: fortis fortuna adiuvat

     (please add an English translation of this quotation)

Often misquoted in English texts as fortēs Fortūna juvat, which uses the accusative plural ending -ēs instead of the accusative ending -īs. Although grammatically correct, the form ending in -ēs is not the one used in Terence's play.

• → English: fortune favors the bold (calque)
