broach (something) to (someone)
To mention or discuss something with someone. I wouldn't broach that topic to him unless you want to hear about it for hours. Everyone knows you shouldn't broach the issues of politics or religion to guests at a dinner party.
dated Of a sailing vessel, to turn or veer in the direction of the wind, exposing the broadside of the ship to it and threatening to capsize as a result. The storm caused the boat to pitch and heave, and, in the chaos of it all, the helmsman allowed the vessel to broach to, overset, and take with it the lives of all onboard.
