Bare means "naked," but to bear is to carry something. A bear is also a brown furry animal, but most people keep that one straight.
To bare is to uncover, either by removing clothes or revealing something. It's getting down to the bare bones. Bare-knuckled or barehanded means the gloves are off. Don't walk on glass in bare feet, and don't bare your soul to a con artist. Let's reveal a few good examples of bare:
In our textbooks, there are photos of physicians a century ago performing autopsies with their bare hands. (Salon)
At a bare minimum the crisis cost nearly $20,000 for each American. (New York Times)
If you can't bear to be naked, you can't stand it. Bear is to put up with or carry something, like a burden or a baby. Or both. It's spelled just like the animal. Grin and bear it means to smile during a storm, not to smile and disrobe. The Second Amendment of the U.S. Constitution mentions the right to bear arms, and it has nothing to do with tank tops. If a tree bears fruit, you're in luck. Here are some non-furry bears caught in the wild:
But he could not bear to live in their dream without the one who was to share it. (Time)
Your son will still be your son, and your grandchildren your grands, no matter what name they bear. (New York Times)
If you can't bear to remember it all, just imagine a lumbering grizzly carrying a heavy load, and you'll bear this knowledge with glee! If a bear bares his teeth, though, run!
