Is the word "extra" dependent on the presence of an original amount greater than zero?
Say you have a piece of cake with no icing...if you added icing would it be considered extra or would the word extra be dependent on having icing to begin with? I am using food as an example because the word extra is very common in the food industry...basically, is adding something where there is none considered "extra" or do you need an oroginal amount of something first?
