how many words can you make with these letters

You asked how many words can be made with the letters in the phrase "how many words can you make." To clarify, are you asking about how many words can be formed using all these letters combined, or are you asking generally how many words can be made by rearranging any subset of these letters? Also, could you please confirm if the space characters are to be considered or only the letters, and if you want words of any length or words with any specific length? This will help me provide a precise answer.
