We gave three deals of grain in tribute to the king.

The customers love it, but the employees think the new system is a pain in the butt.

A primitive element of a Hopf algebra is an element h∈H such that 𝛥h=1⊗h+h⊗1. It is easily seen that the bracket [x,y]:=xy-yx of two primitive elements is again a primitive element. It follows that primitive elements form a Lie algebra. For H=U(g) any element of g is primitive and in fact using the Poincaré-Birkhoff-Win theorem, one can show that the set of primitive elements of U(g) coincides with the Lie algebra g.
