The word "standerbyes" is not found in dictionaries, and it appears to be a misspelling or a rare variant of the word "bystanders". However, I can provide information on the etymology of the word "bystander".
The word "bystander" originated in the 16th century and derives from two Middle Dutch words: "bij" (meaning "by") and "stān" (meaning "stand"). It essentially meant "one who stands near" or "one who stands by". Over time, the term evolved and was adopted into the English language.
The suffix "-er" is also added to the word, which is common in English to create agent nouns. In this case, it signifies a person who performs or is associated with the action of standing by or observing something.
