There are 578 4-letter words containing D in the ENABLE dictionary — 15% of all 3,903 words at this length. D is a one-point tile, so the value in this list is positional rather than numerical — which of these you can play depends far more on where it fits the board than on what it scores.
The D falls in the first position more often than any other, in 233 of them. 21 of them use the letter more than once — adds, dada, dado, dads among them, which is the case worth checking twice when a game has told you a letter is present but not how many times.
If you know more than one letter, this page stops being the fast way to find it. Enter what you have in the unscrambler — the Contains, Starts with and Ends with filters combine, and setting both length fields to 4 narrows this list to the handful your letters actually allow.
