To point out means to call attention to something that others might not have noticed, or to identify something specific among many things. When your teacher points out a tricky word problem on the board, she's making sure everyone sees it. When a friend points out that your shoelace is untied, he's helping you notice something important before you trip.

You can point out things physically by gesturing toward them: “Let me point out which trail leads to the waterfall.” You can also point out ideas or facts during a conversation: “I should point out that we have only twenty minutes left” or “My sister pointed out that my argument didn't make sense.”

Sometimes people point out mistakes or problems, which can feel awkward but is often helpful. If your lab partner points out that you measured incorrectly, she's trying to help you get better results. Other times, people point out positive things: “The coach pointed out how much my batting has improved.”

The phrase suggests making something clear and visible that was unclear or hidden before. When you point something out, you're acting as a guide, helping others see what you've already seen.
