I am very much familiar with the elements of grammar. I probably need only to read more widely to add to my repertoire the small number of structure I do not know. Therefore my question is not "how do I learn learn new ways of structuring sentences"", but "how do I use the ways I already know to create long sentences which are clear and pleasant to read?" I am well aware of the advice that is prevalent these days, which opposes the use of long sentences, but such advice is not acceptable to me, for it is important for me, whether I write long sentences or short, to be able to write long ones, and them clearly. So my question is, how to write a long sentence in such a way that, when read from beginning to end, it is easily and fully understood, revealing its content from clause to clause in the most effective order? What are some strategies, besides writing a completely tangled up sentence and revising it, to accomplish such a feat?
