The story

Borrowed from Middle French sceptique (but with a pronunciation closer to that of the Latin etymon), or possibly directly from Late Latin scepticus (originally attested only in the plural Scepticī (‘the sect of Skeptics’)), from Proto-Italic *spektos (‘see, observing’), from *speḱ- (‘to see’), compare to σκοπέω (skopéō, “to view, examine”).
