Borrowing from French au fait (literally "at fact"). (Wiktionary)

Examples

  • 'Quoique le sauvage du nouveau monde soit à-peu-près de même stature que l'homme de notre monde, cela ne suffit pas pour qu'il puisse faire une exception au fait général du repetissement de la nature vivante dans tout ce continent: le sauvage est foible & petit par les organes de la génération; il n'a ni poil, ni barbe, & nulle ardeur pour sa femelle; quoique plus léger que l'Européen parce qu'il a plus d'habitude à courir, il est cependant beaucoup moins fort de corps; il est aussi bien moins sensible, & cependant plus craintif & plus lâche; il n'a nulle vivacité, nulle activité dans l'ame; celle du corps est moins un exercice, un mouvement volontaire qu'une nécessité d'action causée par le besoin; otez lui la faim & la foif, vous détruirez en meme temps le principe actif de tous ses mouvemens; il demeurera stupidement en repos sur ses jambes ou couché pendant des jours entiers.

    Boiling a Frog

  • He had not the placid, quiet, unworldly air of Simeon Halliday; on the contrary, a particularly wide-awake and au fait appearance, like a man who rather prides himself on knowing what he is about, and keeping a bright look-out ahead; peculiarities which sorted rather oddly with his broad brim and formal phraseology.

    Uncle Tom's cabin, or Life among the lowly

  • He could gobble like a turkey so perfectly as to deceive the most experienced old gobbler on the farm; he could crow so like a cock that all the cocks in the neighborhood would reply to him; he could mew like a cat, and bark like a dog; he could sing and fiddle, and dance the double-shuffle, and was au fait in all manner of jigs and hornpipes; and one need not wonder, therefore, that old Cæsar was hugged and caressed and lauded by me in my childhood as the most wonderful of men.
