Questions & Answers about Mi hermano anda diciendo que el examen oral será difícil.

What does anda diciendo mean here?

Here anda diciendo means something like has been saying, keeps saying, or is going around saying.

It does not mean your brother is literally walking while speaking. The structure andar + gerund adds the idea that he says this repeatedly, casually, or to different people.

So the sentence has more nuance than a plain Mi hermano dice que....

Why is andar used instead of estar?

Both can be followed by a gerund, but they give different shades of meaning:

• estar diciendo = is saying / is in the middle of saying
• andar diciendo = has been saying around, keeps saying, goes around saying

So andar + gerund often suggests a repeated or loosely ongoing action, not just something happening at this exact moment.

In Spain, andar + gerund is very natural and fairly colloquial.

Why is it diciendo and not decir?
