take someone at their word

Believe without proof

To take someone at their word is to believe what they say without requiring proof or reading between the lines: She said she'd pay me back, so I took her at her word.

The phrase implies trust—sometimes warranted, sometimes naive.

It can carry a hint of warning: Be careful taking him at his word.
