"Come" has a long and interesting history:
* Proto-Indo-European: The word's earliest ancestor is believed to be the Proto-Indo-European word *kʷem-, meaning "to come". This word spread throughout different languages as they developed.
* Old English: In Old English, the word was "cuman", which was a strong verb, meaning it changed its form for different tenses.
* Middle English: During this period, the spelling evolved to "comen", and it continued to be a strong verb.
* Modern English: Over time, the strong verb "come" gradually became a weak verb, meaning it uses the same ending for the past tense ("-ed"). This is why we have "came" instead of something like "com" or "cometh".
So, in summary, the word "came" is a result of the evolution of the word "come" through various stages of English language development, ultimately becoming the past tense of the verb "come".
