Secondary roles can often be referred to as supporting or minor roles in a production or project. These roles serve to enhance the main storyline and provide depth to the overall narrative. Other synonyms for secondary roles include subordinate, auxiliary, or supplementary roles. These types of roles may not be as prestigious or highly regarded as the lead roles, but they are equally important in contributing to the success of the project. Supporting roles can also be referred to as non-essential, inconspicuous or insignificant roles. It is important to note that these roles are still crucial in making a production or project successful and should not be overlooked or undervalued.
