When your younger brother runs around the house with scissors, you should definitely object. Perhaps a less sharp object such as a roll of paper towels would suffice.

An object (OB-ject) is something that is a visible entity, something that can be perceived by the senses. If you are unsure whether something is an object, test it by seeing whether it can cast a shadow; if it can, it's an object, if it can't, it's not. In court, lawyers will often say, "I object!" Here, the verb object (ob-JECT) means to express disagreement.
