Recently one of my friends told me that there is distinct difference between 'know of something' and 'know about something' expressions. 'know of' is used when you have personal experience with wha...
I wonder when verbs like think or know are followed by that; I encountered both forms, is there a difference? For example, I know that he did it. // I know he did it. Are the two sentences both
For me, know implies knowledge of details or individual pieces, while am aware of implies a knowledge only of a whole. Using your example, knowing my rights means that I know I have the right to remain silent, the right to be represented by an attorney, etc. Being aware of my rights might mean the same thing, but implies that I know that I do have rights, but am not sure what those rights are.
Possibly, "I do know that" can in fact only be used, when, you are answering the question of whether or not you know the issue at hand (or your knowledge has been called in to question, and you are answering that challenge). Let's say "out of the blue" you wanted to state that "you know that" -- and you wanted an emphatic version.
But there are also unknown unknowns – the ones we don't know we don't know. "Known unknown" implies there are things we know we don't know, while "unknown known" could imply things we know but don't yet realize the value. Thus, there is a difference in meaning.
It's not just you that doesn't know. Now, according to owl.purdue.edu, we should use "doesn't" when the subject is singular (except when the subject is "you" or "I"), and "don't" otherwise. But in the example above, I am having a hard time figuring out what exactly the subject is and whether it is singular.
I've been thinking that the phrase " already know " is different from the phrase " have already known ". Already know: I know something clearly at this point of saying (present) Have already known: I've known something so far. (present perfect) I may be confused in the explanation. I don't know when we can use each of these phrases properly. Thanks and best regards,
Should I use "did you know" or "do you know" to introduce a fact? I've only seen "did you know" in action. My logical deduction is that before the "question" (which is not much of a question because you're not asking for an answer), you wouldn't have been sure whether the listener'd known about what you're about to say or not.
I always took it to mean that of all the attendees, half of them are people he doesn't know as well as he wants to, and less than half of them are people who he doesn't like as much as he should.
