change for words

Bill Bryson’s “Where Words Come From”, I found it very much interesting. It was really very amazing to know that all these words around us neither created by only English speaker nor they had been used to mean the same meaning as they are now. For example, we have been using ‘Nice’ for something which is pleasant, precise, luxurious and elegant but in Latin, it means stupid and foolish. Not only this, some words like enthusiasm, politician, manufacture etc had used to describe something totally opposite. Enthusiasm used for a term of mild abuse which now means a word of praise. Politician was a sinister word and manufacture signified something made by hand and all of these are adopted from Latin in English.
It is almost unbelievable that some words are created just by error. But in English it is really common that some words came from mishearing and somehow their existence is admitted while the original one is forgotten. For instance, buttonhole was buttonhold, sweetheart was sweetard and asparagus was sparrow-grass.
Shakespeare always has been my favorite writer. It was really nice to know that he gifted English vocabulary a bunch of words that nobody uses before him. He created- barefooted, critical, lonely, hurry, countless, excellent monumental etc. I wonder what an English speaker would have said when he felt very alone. How were they able to express their feelings with these right words? I want to say like Bill Bryson, “How would we manage without them?”
