She's writing it the same way she says it. I would ding her for not learning to annunciate properly but training in annunciation is severely lacking at all schools, public, private and home. The bigger issue is that she seems to have no idea what an antibiotic is and therefore never learned the proper spelling. It's one thing to not know the proper names of modern drugs or being unsure of what they're really for. The discovery of antibiotics was one of the great medical advancements of the 20th century, a major medical milestone that every kid should have learned at some point in school. That's where Carlin gets dinged, she either never learned it or doesn't remember. Either way, her spelling is unacceptable.
