I don't think that was her example as it was not connected with the 3 letter word game. I sent an e to my sister to ask if she remembers. I do remember 'ohm' and 'mho' since my eldest brother was a Ham operator. For a four year old I learned a lot of strange words. I basically learned to read off of billboards and road signs once I was out of 'baby books' although we all read very early and we all spent our lives reading constantly.
