___ Marino

SAN

This Hall of Fame quarterback’s first name is also a Spanish word for "holy."

This clue is looking for a short, three-letter prefix that completes the name "___ Marino," which refers to Dan Marino, the famous NFL quarterback. "San" is Spanish for "saint" and often appears in place names or surnames, like San Diego or in this case, as part of Marino’s full name (though it’s not always written that way). The blank hints at a common abbreviation rather than a tricky wordplay—just fill in the missing piece.
