From the time my son was just learning to speak he seemed to love words more than the average kid and because he asked about words he hadn't heard before, even as a toddler, it was like he built a thesaurus in his mind so that whenever he wanted to say something he could choose more interesting words or make alliterative phrases instead of saying it in some boring, cliche way and of course he could come up with all those puns and analogies that he likes to use. Adults where we live don't understand why he doesn't want to talk about football and sports all the time like everyone else.
