In 1906,
U.S. President Teddy Roosevelt tried to get the government to simplify the spelling of 300 common English words. However, this didn't go over well with Congress or the public. In 1906,
Andrew Carnegie was convinced that English could be a universal language used around the world if only English was easier to read and to write. In an attempt to tackle this problem, Carnegie decided to fund a group of intellectuals to discuss this issue. The result was the Simplified Spelling Board.
The Simplified Spelling Board was founded on March 11, 1906, in New York. Included among the Board's original 26 members were such notables as author Samuel Clemens, (Mark Twain,) library organizer Melvil Dewey, U.S. Supreme Court Justice David Brewer, publisher Henry Holt, and former U.S. Secretary of the Treasury Lyman Gage. Brander Matthews, professor of dramatic literature at Columbia University, was made the chairman of the Board.
The Board examined the history of the English language and found that written English had changed over the centuries, sometimes for the better but also sometimes for the worse. The Board wanted to make written English phonetic again, as it was long ago, before silent letters such as "e" (as in "axe,") "h" (as in "ghost,") "w" (as in "answer,") and "b" (as in "debt") crept in. However, silent letters were not the only aspect of spelling that bothered these gentlemen.
There were other commonly used words that were just more complex than they needed to be. For instance, the word "bureau" could much more easily be spelled if it was written as "buro." The word "enough" would be spelled more phonetically as "enuf," just as "though" could be simplified to "tho." And, of course, why have a "ph" combination in "phantasy" when it could much more easily be spelled "fantasy."
Lastly, the Board recognized that there were a number of words for which there already were several options for spelling, usually one simple and the other complicated. Many of these examples are currently known as
differences between American and British English, including "honor" instead of "honour," "center" instead of "centre," and "plow" instead of "plough." Additional words also had multiple choices for spelling such as "rime" rather than "rhyme" and "blest" rather than "blessed."

The reason that Spanish is a simpler linguistic language is because, like all Latin based languages it follows the Latin structure. English has many languages, that sit side by side, then we had a fellow name of Shakespeare, who not only created new words, he jumbled up a good deal of what was there. He also dropped the Latin based verb endings and so much more.
Did you know that despite there being in excess of 273,000 words, English is still the first choice for those whom it's not their mother tongue, to learn? That's resulted in 1.35 billion people being able to converse in English.
