This talk will cover key elements of the Electroweak (EW) sector of the Standard Model (SM). I will firstly review the underlying structure and general features of EW interactions, from the well known Spontaneous Symmetry Breaking (SSB) mechanism to the complex-mass scheme for the decay of weak gauge bosons. An overview of relevant related topics, such as the Goldstone Boson Equivalence Theorem (GBET), will also be discussed. Finally, I will briefly address the behavior of EW corrections at high energy. In this regime, one-loop EW corrections are logarithmically enhanced and in tail of kinematic distributions can yield correction factors of several tens of percent, reaching a similar size to the corresponding QCD ones. Thus, a very good control of these effects, and of remaining theoretical uncertainties, is crucial for the success of many physics endeavours at the LHC.
