Word of the Day (Part 2)

I think my son may be reading the dictionary on the sly (thought I'm not sure when he learned to read...). This morning he used the following word:

Duplicitous: (adj.) given to or marked by deliberate deceptiveness in behavior or speech.

Granted, he didn't use the word in the correct context, but we're amazed he even knew how to pronounce it.

"Daddy, did you know taxes are duplicitous?"
