You answer must be directly related to the Category. (Eg. "Refrigerator" is not "A Boy's Name")
Simply start your answer with one of the letters that is displayed: type it in with the keyboard and press submit.
Answers cannot start with articles. "The", "An" and "A" cannot be at the beginning of any answers. (Eg. "The Offspring" does not count as a musical group beginning with T, but "Offspring" does count as a musical group beginning with O).
