Ex Input:
Possible Duplicate: Does 'notified by [date]' include the end date? When someone says 'I will do it by Monday', does it mean that they will get it done before the beginning of Monday or before the end of Monday?.

Without further context, it generally means before the end of Monday. Now end can be defined as midnight, bedtime, end of work day, or any previously discussed time, depending on context.

Ex Input:
Someone told me that I shouldn't use the phrase discuss about, but should say, instead, discuss (the topic). He said discuss means talk about and using discuss about is like saying talk about about, which is redundant. Is he correct? Could somebody elaborate on this?.

Ex Output:
Your friend is correct. You can discuss something, or you can talk about it, but discuss about is redundant for the reason you identified. discuss: to speak with another or others about But if you want to use the word about, you can have a conversation about, confer about, debate about, or even have a powwow about. Most of the other synonyms for discuss don't take about, nor is it needed to converse (or debate).

Ex Input:
I've heard people say 'be king' (as in 'I can't wait to be king') in movies and TV. Why don't they say 'be a king'? Which is correct?.

Ex Output:
Since 'a king' uses an indefinite article, it suggests that he may become any one of a number of kings. In most cases where a person may become king, there is only one king in the political structure he inhabits. For instance, if he is in the line of succession for the English throne, he probably cannot become king of France or Denmark without marrying into that royal family. The equivalent phrase to 'I can't wait to be king' would use a definite article - it could be rephrased as 'I can't wait to be the king', since there is only one kingship he is eligible to accede to.
