Why sometimes the word 'do' is added to the verb in an affirmative sentence?
Today I read this in a website: "But we do know that women who have diseases..." and I have seen many times the word 'do' in addition to the verb in affirmative phrases. That 'do' would not be necessary, so, why is it used? What is its purpose? How do I know when and how use that structure?
Thanks in advance!

Question

Answer

Good question.  Here is meant to exaggerate your verb "know", similar to saying I absolutely know.  We may use this form when a person has been saying a list of things they don't know and then they want to make sure you know they at least know this other thing.

For example:
We don't know the color, the shape or the price, but we do know where it comes from.

Answer

Es como--Pero sí sabemos que las mujeres que tienen enfermedades.

Answer

The best response I could give you for this question and this is very confusing when learning the English language, knowing when to use do, does and did. For this reason I would like to share this page with you and I hope this will help you understand when to use *do* with a verb in a sentence. Continue your good work there :) Here is the page: http://www.gingersoftware.com/content/grammar-rules/verbs/do-does-did/
