There are no negatives in the phrase "father and us".
Spanish uses double negatives, so this literally translates to: "He/she/you can't see nothing" or in English: "He/she/you can't see anything".
Until the modern period of English, a string of negatives reinforced each other. When we said "not no one, not nohow" it meant "absolutely no one at any time." Under the misguidance of "experts" who held that English should be forced to comply with the rules of Latin grammar, in which a series of negatives cancel each other, the "double negative" became an emphatic positive. Thus "not no one" now means "many people."
Well it depends on what the negatives are for example if it is "no I didn't" then that statement is still negative but if it is something like "no I never" then 1. That is incorrect grammar 2. that is a positive statement as the two negatives will cancel out.
A double negative is just when a writer uses two negative words together to express one thing, as in "I can't not go." (Meaning I need to go). Although this is common usage, it is less often acceptable in formal writing. Sometimes it is acceptable if it is done well. :) Here is the article from dictionary.com for further reading: http://dictionary.reference.com/browse/double%20negative Example of :Double negative I have the answer to question 20 I got this right.
