Re: Write to him or write him? Hi David27,
You're correct that there is a distinction between 'a' and 'b' - 'a' is North-American English and in British-English you must use 'to'.
In 'b' it is possible to omit 'a letter' in B-E because it's assumed you're going to write a letter (as opposed to a newspaper article).
Hope this helps,
