How to Write Clearly, written by the Rev. Edwin A. Abbott, is a great paradigm of archaic English language. It was first published in 1876 and gives a lovely example of language as it was nearly 150 years ago. Abbott was an English schoolmaster, becoming headmaster of the City of London School at the tender age of 26. He was educated in mathematics, 'classics' and theology and after his retirement in 1889 he devoted the majority of his time to theological and literary pursuits.
Although the book is somewhat dated in its relevance to today's world, it is still of historical significance and is a great read for anyone interested in the progression of the English language. His clear and concise instruction leaves nothing to be questioned and is still very understandable today. It is a great book, with much information still usable today, albeit with a bit of tweaking!
It is a lovely book that will give you a glimpse of a bygone era as well as being informative and interesting; a really good read for anyone with a passion for language.
