There is a duality of structure (structure and action are two sides of the same coin). E.g., Language = a structure made up of a set of rules of grammar governing how we expressmeanings otherwise not understood.
Giddens' structuration theory (2)
Structure also depends on action. E.g., a language would not exist if no one used it, its produced and reproduced over time through the actions of individuals speaking and writing it.
Reproduction of structures through agency
Rules - the norms, customs and laws that govern action
