What Is The Correct Grammar On The Letter I Am Writing

Is "I write letter" grammatically correct? Can it be used as an example for a simple present tense?

When we say, “I write…” using the present simple tense, we are making the statement that this is my habit. The problem is that since “letter” is countable, taking singular and plural forms, the singular always denotes an instance of the abstraction, and does not denote the abtraction itself, to which a habit would refer. To fix this, we need to say, “I write letters” to express habitual activity.If we are actually writing now (or during the current period), we need to show this current activity by use of the present continuous, “I am writing…”Since letter is countable, we must stipulate what category of letter we are writing. If we have referenced the letter before, we say, “I am writing the letter”. Otherwise, we could not be so “definite” and could not use the definite article, “the”.In this case, although we are actually writing a real letter and not referring to an abstract activity, we use the indefinite article, “I am writing a letter”.If your native language lacks articles, you are right to be confused by them. The so-called “rules” governing their use are a messy and imperfect description of standard usage.

Which one is correct, “I am writing to let you know that I arrive tomorrow at 4 PM” or “I am writing to let you know that I am going to arrive tomorrow at 4 PM”?

Check the logical syntax. If the addressee is also the reciever of the written notice, here are the situations.I am writing to let you know that I arrive tommorow at 4:00PM. (The writing and knowing has a long gap, and the arrival of the notice may come first before the knowing). Most likely the distance between of them is not just located accross the street.I wrote this (letter that you received) to let you know that I am arriving at 4:00 PM tomorror.I am calling to let you know that I am arriving at 4:O0 PM tomorrow. (The calling ang knowing has coincidence.)Maybe the writer may come first than to the arrival of his written notice due to the delay of the postman or the courier.We have to consider the facts on writing, recieving of the notice and the arrival, if they have logical relation.

Is the sentence 'I write a letter' in any way grammatically correct?

There is nothing grammatically wrong with the sentence. But it doesn't have much meaning without context, and would likely not be uttered in isolation.It could be part of a longer sentence: "I write a letter to my mother every week."It could be a response to a question:     "What do you do when you are unhappy with your Senator's vote?"     "I write a letter."It does not mean the same thing as "I am writing a letter."

So, if you think you could be of help in this matter and if you have the time and if you wouldn't mind, then I was hoping I might take the opportunity to try phoning you to talk further about it prior to next week, if that would be agreeable to you.”You could.But why not just say,“Thomas Jones suggested I write to you.
