I don’t speak French, but I have always pronounced the past tense of the French-origin word “debut” as
debyooted in English, not
debyood. I just decided that this follows from the American pronunciation of the noun “debut” as
dei’bju, in which case the “t” won’t be silent when the “-ed” for the past tense is added.
Now that you ask, however, I checked with
The Free Dictionary on the web and found that both pronunciations are acceptable. I am unable to reproduce the symbols for the pronunciation key here, but you can check them out by clicking this link to the
citation from The American Heritage Dictionary of the English Language.
So take your pick of whichever pronunciation you are more comfortable with.
