After spending some time on the English SE, I noticed that everytime someone referred to ELL, they always did so by saying "our sister-site ELL".
As I understand, there is no grammatical gender in English. For example, dictionaries do not specify any gender, even for nouns clearly gender related like woman.
Someone said in an answer "We divide things into male people, female people, and everything else.". A website is in the "everything else" category. How come the word that is used before site is sister, and not brother or a mix of both or even a gender-neutral word?
