Matthew Dick thought of the cryptic way of popping the question to girlfriend Delyth Hughes, and persuaded the newspaper to agree.
Yesterday's Times crossword opened with one across: "Pretty Welsh girl widely thought not to be all there." The answer: Delyth.
Other clues included "'Will you marry me,' say, that's forward also rude." The answer was proposal.
Dick says he showed Hughes the crossword at breakfast, with some key words underlined, then "reached into my pocket to reveal the ring."
Times crossword editor Richard Rogan said the proposal was "a one-off" wouldn't be repeated.
