Why it is toothbrush, not teeth brush?It is said that for learning, one should never feel shy in asking questions.
I have always been perplexed with one such question. The question is as to why a toothbrush is not called a teeth brush.
Have you seen any individual with a singly tooth and cleaning his/her single tooth with the toothbrush. Only infants have a single tooth, but they also generally don't clean the same with a toothbrush.
Most of us have a set of thirty two teeth and clean the same at least once in a day in the morning using the misnamed ubiquitous toothbrush. Then why it is not called a teeth brush?
Will you please enlighten me about the subject matter?
