English has MANY words for things. A sandwich can be a sandwich, a snack, dinner, a tuna sandwich or a grilled cheese. A dog can be a puppy or a guard dog or a pet or a beagle or a poodle. A flower might be a tulip or a gift. A gift might be a present, or a birthday present.
Not just English! The quote above is from a discussion years ago in which someone recommended using one single word for each thing, when talking to a young child, and not to use baby talk.
Experienced unschoolers merrily disassembled her theory and built something prettier.
