Neither Pine nor Apple in Pineapple

Have you ever asked yourself (1)why people often have trouble learning English? I hadn’t, until one day my five-year-old son asked me (2)whether there was ham in a hamburger.There isn’t.This made me realize (3)that there’s no egg in eggplant either.(4)Neither is there pine nor apple in pineapple.This got me thinking (5)how English can be a crazy language to learn.
