Cartoonish vs. Cartoonlike

Right: Her art has a cartoonlike quality that I enjoy.
Cartoonlike refers to something that has the appearance or essence of a drawn or animated cartoon. Cartoonish, on the other hand, has the negative connotations of exaggerated or overblown (like a caricature). You might not mind people referring to your artwork as cartoonlike, but you’d probably object to them calling your makeup cartoonish.

Right: We sent them a lovely poinsettia for Christmas.
Poinsetta is simply a misspelling of poinsettia.
I have more, so stay tuned.
