“attest” in Latin

The English word attest itself goes back to Latin testis, through attestor.

Riddle & Arnold A Copious and Critical English–Latin Lexicon, 1864

attest
bear evidence to: testari (general term): attestari: testificari: testimonio confirmare (confirm by one’s evidence): testimonio esse: testem esse (to be a witness: the former of things, the latter of persons): affirmare (to affirm positively): clamare (to cry out).
Call to witness: testari aliquem, testem facere aliquem: God, Deum testari or Deum invocare testem: gods and men, deos hominesque testari, or contestari: antestari aliquem (in legal matters, before the introduction of a cause into court. The question put was, licet antestari? If the party consented, the person appealing to him touched the tip of his ear. In nonjudicial matters it occurs only in Cic, pro Milone, 25, 68).
