Apart from that meaning, you can use verdad in statements and questions when asking someone to accept or corroborate what you’re saying.
Les dije la verdad. I told them the truth.
Hace mucho frió, ¿verdad? It’s cold, isn’t it?
No les gustó, ¿verdad? You didn’t like it, did you?
As you can see from the examples above, verdad translates any kind of English ‘question tag’, such as isn’t it, did you, and so forth. Less commonly, you can put verdad at the beginning of the sentence:
Les dije la verdad. I told them the truth.
Hace mucho frió, ¿verdad? It’s cold, isn’t it?
No les gustó, ¿verdad? You didn’t like it, did you?
