However, depending on the context, you could use:
* κυρία (kyria): This is the most common and generally accepted way to address a woman. It's equivalent to "Madam" or "Ms." It's polite and doesn't specify marital status. This is the best and safest option in most situations.
* You could add a surname: You could use κυρία [surname] (kyria [surname]). This is a formal and respectful way to address a married woman, but again, doesn't explicitly state marital status.
Therefore, simply using κυρία (kyria) is the recommended and most appropriate translation in almost all cases. Avoid trying to directly translate "Mrs." as there's no precise equivalent that's naturally used in Greek.
