Marked or annotated with an asterisk (the * symbol).
From asterisk (from Greek asteriskos, 'little star') plus the English past participle suffix -ed. The asterisk symbol resembles a small star, which is reflected in its Greek root.
Medieval scribes loved the asterisk because it literally looked like a tiny star on their manuscripts—so they named it after the Greek word for star. Today we use it mainly to mark footnotes and corrections, but it's also the symbol for multiplication and wildcard searches.
