My class found several mistakes on the morpheme sheet 6 for Spanish II. There are not enough spaces for “demonstrar” and on the back the “to” is missing in front of demonstrate. Monstrar also didn’t have enough spaces. There is no “to” in front of assimilate on the back. Also there were not enough spaces for demonstración.
In Spanish the word for demonstrate and its variations do not contain the letter “n”. The same is true for mostrar and demostrativo which frequently appear incorrectly in print. The reasons are buried somewhere in my old phonetics and linguistics books, language nerd that I am. Hope this helps your Spanish II kids. Mine make the same mistakes. Suerte with the end of the year.
