PROBLEM: Question: I am creating a computer game in which the character needs to consume food in order to not starve to death. In the game I can display the level of how much food the character currently needs via "hunger level" - the higher this value, the more desperately the character needs food. But what I want now is to turn that around, so that this level tells how full the stomach of the character is. In German we have a word for that, "Sattigung", which means how full my stomach is (or better: how full it feels to me), it is basically the opposite of hunger. Is there a similar word in English, which means exactly that, the opposite of hunger? It might be something like "saturation", but from what I can tell this word is usually used in a technical context, like in "the saturation of a color". Can I use that "saturation" to describe the opposite of hunger of a human or animal, or is there a better word for that? 
Answer: I think the apter word is 'satiety' than 'saturation' in the OP's context. satiety thestateof beingcompletely satisfied,especiallywithfoodor pleasure, so that you could not have any more.

SOLUTION: yes

PROBLEM: Question: is it 'a usual' or 'an usual'? 'A usual' sounds more correct in my head ('Today was a usual day.') than 'an usual', but u is a vowel. Which one is correct and why? 
Answer: The technical definitions are: open vowel sounds or closed vowel sounds. All open vowel sounds such as, orange, envelope and image require the article "an" to bridge the two open sounds. Closed vowel sounds typically start with an unwritten "yu" consonant such as "a university" or "a united Europe, a Europe which is united" and therefore use the more common "a" article.

SOLUTION: no

PROBLEM: Question: In a few days, I have to do a class presentation project about the 1920s Harlem Renaissance. I want to say that the movement's original name was the "New Negro Movement," but I'm not sure if that's okay. I'm white, and I really don't want to offend anybody in my class. Is it all right to say this word in context? Or, should I ignore its original name, and only refer to it as the Harlem Renaissance? 
Answer: In a historical or literary context, in my experience you can always use "negro," "nigger," etc. Try to avoid it if possible of course, but if it comes down to using the word or awkwardly skirting around it, always choose the former. For example, in a literary paper, don't do this: "Miss Watson's big [N-WORD], named Jim, was setting in the kitchen door; we could see him pretty clear, because there was a light behind him." (Twain 58) And in the case of your presentation, you are of course allowed to say "New Negro Movement." Just note that it is a term that some people may find offensive, so be mature about it. Note the first part, "in a historical or literary context." This does NOT give the excuse to throw the N-word around.

SOLUTION:
no
