Structuralism is a method that, for example, sees an axe not just as a tool, but as a sign in a complex system. This is a shift from an emphasis (in anthropology) on function to communication.
Structuralism is a point by point refutation of existentialism, focusing on the anonymous systems and structures which precondition individual experience rather than on the individual first-person experience of the self-responsible individual (i.e. Existentialism).
Structuralism is a method of analysis whereby, much like with the negative image of a photography whereby every point is changed and yet the image is fully recognizable, constant relations are drawn from elements that in themselves, in their own character, in their substance, can change.
Structuralism is a step back from structural functionalism insofar as the mind is seen as tending toward a resolution of the binaries (cultural dissonance) that it itself creates.
Structuralism is a mode of analysis whereby what counts in essence are systems of relations and thus not at all the lived individual experience of people.
Structuralism is a methodological approach that attempts to show that human action is determined by structures that are unknown to the agents whose actions they determine.
Structuralism is a meta idea that suggests that different aspects of social life (e.g. Art, religion, myth, kinship, etc.) are constructed in their inmost nature like language.
Structuralism is a refutation of existentialism in that it is does not concern first-person humanist historical processes, but anonymous systems, non-agentive invariant structures.
