Recently I was been posted with this question: Why is  1. I don't know who is he. (grammatically incorrect) 2. I don't know who he is. (grammatically correct) Even as a native English speaker, I could not give the person asking this question a definite answer or explanation. Please enlighten me on this. Thanks!

Lets consider the following:  The book doesn't explain, &quot;What's the wisdom behind education?&quot;  Changing this to an indirect question becomes the following:  The book doesn't explain what the wisdom behind education is.  Now, I found many instances on Google where structures like this weren't really converted to indirect questions. For example:  The book doesn't explain what's the wisdom behind education. &quot;[She] doesn't say what's really on her mind.&quot;  Edit: And consider the following:  What's the logic behind it. (a) I wonder what's the logic behind it vs. (b)I wonder what the logic behind it is.  (a) sounds better but why? And are these constructions acceptable?

To mean "He is a friend of mine who I love" or "He is a friend of mine that I love", can I say "He is a friend of mine I love"? When I omit "who" or "that" in that sentence, it sounds wrong to me. I think I am not used to that structure. What do you think?  Note: I know (that) relative pronouns can be dropped like in "He is someone (that/who) I love", but in the sentence I gave, I think it is wrong to omit it because "a friend" was already modified by "of mine".  Context: I am talking about a friend, and I am saying I love him.

An ELL post () says     I don't think I understand what kind of buttonholes they're talking about.   I found "I don't understand" is commonly used to express the unawareness of something.     So, what is the difference between "I don't think I understand" and "I don't understand"? Is the latter more formal than the former, therefor no published book uses the former?  Could someone please give a hint? Thanks in advance.  On Google, "I'm not sure I understand" got 17,300,000 hits, "I don't think I understand" got 48,500,000 hits, "I don't understand" got 162,000,000 hits.

On the subject of "whoever" and "whomever", I was reading this but I am still confused:   What is the correct use of whoever/whomever in the following sentence?     I like your copy, congratulations, whoever is writing it.   Whoever? Whomever?   Is there a difference between US and UK English?

In this case what is correct?        Keep Tom and I updated.      or         Keep Tom and me updated.      I understand that me is an object pronoun. And therefore I feel the second option is correct.  Especially, because I would say "Keep him updated" and also "Keep me updated". Instead of "Keep he updated" or "Keep I updated". But something about saying "Keep him and me updated" feels wrong.  However I am not sure, because several people have told me that in this case I is the correct option because it is being used in conjunction with a name (Tom) and not a pronoun. Is that correct?

I have some doubts about the usages of That and Who. Sometimes I read sentences such as. "You are someone I love" "You are someone WHO I love" Or "People were asked to describe the qualities they look for in a friend" "People were asked to describe the qualities THAT they look for in a friend"  Why in some of these sentences WHO or THAT are omitted and others are not. Could somebody help me with this? I'll appreciate it! Thanks a million.

I know there are different opinions on this issue. My question: Is using "he" for a general, gender-neutral third person still in common use for formal writing? By common use I mean, can I expect my paper not to be penalised because I use "he" as pronoun for "a student", etc.?   I think "he/she" is too clumsy and I am not comfortable with singular they.

Q: "Don't you know?"   If I really don't know, how should I respond to this question? Yes or No?  There's a similar question on EL&amp;U, but the answer isn't clear how it works:      Also here on ELU too:      These answers are confusing. I want to know what one word answer I can use. In other words I want to know:   What will native speakers understand if I reply No to this question? What will native speakers understand if I reply Yes to this question?

My friend and I got into an argument about English grammar, so I was hoping maybe you could help us out. Okay so we want to know if the following part of the sentence is correct, "People who are satisfied and feel self-fulfilled like I" rather than "People who are satisfied and feel self-fulfilled like me". I have already provided many sources to my friend showing that the first way is a formal and a grammatically correct way, however he wants an answer with this specific part of the sentence.   Please help us out  Thank you

I read an English grammar article in which the author talked about the correct use of pronouns.  He writes:     If the extended sentence is “She’s more likely to ask him than I am,” in which the comparison is between the subject and the writer, I is correct. However, if the intent is to convey that the man referred to as him is more likely to be asked something by the subject than the writer is, the correct pronoun form is me, but that distinction should be clarified with a revision like “She’s more likely to ask him than ask me.”   Before reading this piece, I thought that the two sentences had the same meaning. While the second example is quite clear for me (“She’s more likely to ask him than ask me”), I don't think that I have correctly understood the first one. Could anyone explain it to me, please?

I'm always confused when it's correct to use "Me" and when it's correct to use "I"?   Can I always replace "I" by "me" (not opposite)?  Some examples:  "Me and you went together there"  "I and you went together there"   For the moment I'm using me just in the end of the sentence or when I'm talking about me and someone else together. But I sometimes hear people that replace the two pronouns. Maybe here I'll solve the problem and I'll Know what is the correct way.

I happened to watch a lecturer was explaining word order of English in the beginners’ English learning course in NHK’s - Japan’s largest and publicly-owned broadcasting network – educational TV program (aired on July 23rd). He showed four cubes, each of which showing the word, “Who”, “You” “Help” “Do” placed at random, and asked students to put the cubes in the right order:   Right answer: Who Do You Help?   I was comfortable with “Who do you help (speak / give / write, and so on) too, but a question arose:   Is “Whom do you help?” grammatically wrong or, obsolete? If so, why is it wrong, how and around when it became obsolete?  I’ve never seriously thought of such question as the declension of a dative pronoun in interrogative form until I hit upon the above TV scene. Taking advantage of this opportunity, I ventured to post a beginner’s question.
