If your brother-in-law is your wife's brother, then his sister is either your wife or one of her sisters and thus your sister-in-law.
If your brother-in-law is your husband's brother, then his sister is your sister-in-law.
If your brother-in-law is the husband of your sister, then his sister is not related to you, but is your sister's sister-in-law.
If you're particularly close - And she's older than you - "Aunt" sounds fine
AnswerYour uncle's sister-in-law may be the wife of your uncle's brother. If your father is the brother in question, you would call her "Mom." Otherwise she might be your aunt.
Your uncle's sister-in-law might also be the sister of your uncle's wife. While his wife is your aunt, the wife's sister is not related to you.
Your sister's husband is your brother-in-law, so your brother-in-law's wife could be your sister.
The brother of your spouse is also your brother-in-law. In that case his wife is not related to you, but is sister-in-law to your spouse.
If you are referring to your brother's brother-in-law from his wife's side of the family- they are not related to you.
When your brother-in-law is your spouse's brother, his sister is also your spouse's sister and so is your sister-in-law (unless she is your wife).
When your brother-in-law is your sister's husband, hissister is not related to you, but is your sister'ssister-in-law.
Your brother's mother-in-law is not related to you.

Your aunts and uncles are the sisters and brothers of your parents. So they are "blood related." But you also call the husband of your mother's sister your uncle, and he is not "blood related." So aunts and uncles are not always really related to you.
Your parent's brothers are your uncles and your parent's sisters are your aunts.
No, "uncles" does not have an apostrophe. An apostrophe is used to indicate possession or to form contractions, but in the case of "uncles," it is simply a plural noun.
Your uncle/aunt's son/daughter is an adult and you are still small, your uncle/aunt's daughter had a child, and that child will call you uncle. Uncles/aunts are your dad/mom's siblings.
Cousin. Your parents brothers and sisters are aunts and uncles. and the aunt and uncles children are your cousins.
Chiron, Bythos, Aphros would be uncles by Kronos and Philyra; by Kronos and Rhea her uncles are Poseidon and Hades, both brothers of Zeus are her uncles; on her mother's side she did not have uncles.
