It is a common expression used to show politeness, particularly when meeting someone for the first time or expressing gratitude. It translates to "I'm delighted" or "I'm charmed" in English.
For example:
* "Encantada de conocerte." (I'm delighted to meet you.)
* "Encantada de haberte ayudado." (I'm charmed to have helped you.)
* "Encantada, ¿qué puedo hacer por usted?" (Delighted, what can I do for you?)
The word "encantada" literally means "enchanted," but its usage in this context has evolved to express a more polite and positive feeling.
