Answer:
While it might seem like a big name, symbolic interactionism is how your experiences add subjective meanings to symbols and letters. For example, the word 'dog' is just a series of letters. Through your interactions with the letters 'dog', you see this as a furry, four-legged canine.
Gender can be understood through symbolic interactionism because gender is a sociological construct. For example, for the symbols attached to “males” and “females”, actions and looks are based on what is believed is true from your interactions rather than what is objectively true.
