Thanks. To answer your questions: The letter "W" is a semivowel or glide, which means it has characteristics of both a consonant and a vowel. Generally, it is considered a consonant, but it becomes a vowel when paired with "a," "e," or "o" to spell a single sound, as in words like "draw," "few," and "low". I included it in the caveats because I wanted to make sure people will know.
