Reason with

1. Definition + Rich Everyday Explanation

Reason with (phrasal verb) = to try to persuade someone to act sensibly or change their mind by presenting logical arguments and calm discussion.

When you reason with someone, you’re attempting to reach them through logic rather than emotion, force, or authority. You’re not shouting, threatening, or demanding. You’re not pulling rank or using power. Instead, you’re appealing to their rational mind, hoping that calm explanation will help them see things differently.

The phrase often appears in situations where someone is being unreasonable — acting emotionally, stubbornly, or irrationally. A parent tries to reason with a tantrum-throwing child. A friend tries to reason with someone making a terrible decision. A negotiator tries to reason with someone in crisis. The implication is that the other person isn’t currently thinking clearly, and you’re trying to bring them back to rationality.

Importantly, reasoning with someone doesn’t always work. In fact, the phrase often appears in contexts where it fails. “I tried to reason with him, but he wouldn’t listen.” “There’s no reasoning with her when she’s like this.” “You can’t reason with someone who’s already made up their mind.” This reflects the frustrating reality that logic alone often can’t overcome strong emotions or fixed beliefs.

The phrase suggests patience, respect, and good faith. When you reason with someone, you’re treating them as a rational adult capable of changing their mind — even if they’re not currently acting like one. It’s a more dignified approach than manipulation, coercion, or simply giving up.

Examples from the street:

• “I’ve tried to reason with her, but she refuses to see any perspective other than her own” → I’ve attempted calm logical discussion, but she won’t consider other viewpoints
• “There’s no reasoning with him when he’s angry — wait until he calms down” → logical arguments won’t work while he’s emotional; patience is needed
• “Maybe you can reason with her — she won’t listen to me” → perhaps you can persuade her through logic since she’s ignoring my attempts
