Experienced; having knowledge or skill gained from practice or observation.
From Latin 'experiens,' present participle of 'experiri' (to try or test). This is a rare or archaic form of 'experienced,' preserving the Latin participial form in English.
This word is so archaic that even most English teachers haven't encountered it—it's essentially a museum piece, an old way of saying 'experienced' that's been replaced by more modern forms. Literature from the 1600s used it, but it died out.
