άλλων
"Άλλων" means "of others" or "of other people" in English.
Here, "άλλων" is used as a possessive pronoun in the genitive case to indicate possession ('of others').
Η βοήθεια των άλλων μας είναι πολύτιμη.
The help of others is invaluable to us.
In this sentence, "άλλων" functions similarly as a possessive in the genitive case, specifying the entity ('of others') whose opinion is being referred to.
Η γνώμη των άλλων δεν πρέπει να μας επηρεάζει.
The opinion of others should not affect us.
Here, "άλλων" again serves as a pronoun in the genitive case, indicating the source ('of others') of the mistakes discussed.
