dialogar

To dialogue or hold talks — used for a formal, structured exchange of views, often between opposing sides: dialogar con la oposición, dialogar sobre el conflicto. More formal than the everyday hablar, and common in political and diplomatic language.

• El gobierno se comprometió a dialogar con los sindicatos. — The government committed to dialogue with the unions.
• Es importante dialogar antes de llegar a un conflicto mayor. — It's important to talk things through before reaching a bigger conflict.
• Las dos partes finalmente dialogaron para resolver la disputa. — The two parties finally held talks to resolve the dispute.

Using dialogar for a casual chat between friends — it implies a purposeful, often formal exchange meant to resolve something; for ordinary conversation, hablar or charlar is more natural.

Often confused with hablar.
