* Proto-Germanic: *wordō* (meaning "word", "speech", or "utterance")
* Old English: *word* (meaning the same)
* Middle English: *word* (meaning the same)
* Modern English: *word* (meaning the same)
So, the word "word" has been around in the English language for a long time, with its meaning staying relatively consistent.
However, "wordō" itself might have come from an even older, unknown root. Some linguists believe it might be related to the Proto-Indo-European root "*we(r)-*" (meaning "to speak" or "to say").
Interestingly, the word "word" is also related to the German word "Wort" and the Dutch word "woord", highlighting the common linguistic heritage of these languages.
