Deductive Reasoning Applied to Language

Callia used to be pretty good about switching tenses, but lately she has been adding extra syllables. Just now she said "think-ted", instead of thought, and "catch-ted" instead of "caught". Yesterday she said "cauchted" (cawch-ted) for "caught". Very creative. It comes from the same mind that decided a long while back that since "clothes" means more than one piece of clothing, then a single item, such as a shirt, would be a "clo". :) Like when I'm folding one of my shirts she would ask "Mommy is that your clo, or Daddy's?" She really is a smarty, but her assumptions get her in trouble with our disorganized language. Deductive reasoning does not work with English.
