Semiotics is the study of signs and symbols. In society, we interpret numerous signs and symbols in our everyday lives. However, a sign is not a sign until it is interpreted as a sign.
There are many signs and symbols that we give meaning to. For example, the gender sign is universally understood as Male and Female. Furthermore, these signs signify another meaning, toilets. A recent debate surrounding transgender bathrooms have created a third sign. This new sign is reliant on a cultural agreement that those who identify as transgender will be classified by this symbol.
