1. An airfoil assembly for a turbine engine, the airfoil assembly comprising:
an airfoil comprising a wall bounding an interior and defining an exterior surface, the wall extending between a leading edge and a trailing edge to define a chordwise direction, and between a root and a tip to define a spanwise direction;
a trunnion having a flared socket with an open top;
a spar extending from the flared socket, through the open top of the flared socket, and into the interior of the airfoil, and the spar having a first end located in the flared socket;
an insert received within the flared socket; and
a skin, including a braided or woven composite, extending along at least a portion of the spar and the insert.
