Wait, maybe it's "Odín" which in Spanish is often written as "Odin", but that's two letters? No, Odin has three letters. Wait, maybe it's a different mythological figure? Or perhaps the answer isn't Odin. Let me think again. If the clue is the husband of Edda, and Edda here refers to the myth, then Odin is correct. But the two-letter solution... Maybe the answer is "Od" as in Odin's name? But "Od" isn't the full name. Alternatively, maybe in Spanish crossword clues, abbreviations are common. Or perhaps the answer is "O.D.", but that's more like initials.
