Señor’s send-off

As a detective, I knew the key to solving this mystery was in understanding the language and culture of the clue. ‘Señor‘ is a Spanish title of respect typically given to an elderly man or gentleman, indicating that the clue likely had a Spanish connotation. I turned to my knowledge of the Spanish language and recalled that ‘adios‘ is a common Spanish phrase used to bid farewell. Putting the pieces together, it became clear to me that ‘Señor’s send-off‘ was referring to this Spanish phrase. I also considered word play and the fact that ‘adios‘ could be spelled with a crossword-friendly five letters, which further cemented my answer. With a sense of satisfaction, I filled in ‘adios‘ as the solution to the crossword clue, feeling confident that my detective skills had solved another mystery.
