We discuss our present understanding of the transverse spin structure of the nucleon and of related properties originating front parton transverse motion. Starting from tire transversity distribution and the ways to access it, we then address the role played by spin and transverse momentum dependent (TMD) distributions in azimuthal and transverse single spin asymmetries. The latest extractions of the Sivers, Collins and transversity functions are also presented.

Abstract
We discuss our present understanding of the transverse spin structure of the nucleon and of related properties originating front parton transverse motion. Starting from tire transversity distribution and the ways to access it, we then address the role played by spin and transverse momentum dependent (TMD) distributions in azimuthal and transverse single spin asymmetries. The latest extractions of the Sivers, Collins and transversity functions are also presented.
