Terms Involving “In-law”

There are several of these, but most give little difficulty to native speakers. Any relationship term ending with -in-law indicates that the relationship is by marriage and not by blood; in other words, one of us is a blood relative of the other’s spouse.

If I want to refer collectively to the blood relatives of my spouse, I can call them “my in-laws". Sometimes this term means just my spouse’s parents; other times it can mean any group of my spouse’s relatives.

In-law relationship terms are always written with hyphens, by the way. And the plural is formed on the part before the “-in-law”; for example, “brothers-in-law” and not “brother-in-laws”. The only exception is the general term “in-laws”, which is always plural.
Father-, Mother-, Son-, and Daughter-in-Law

My father-in-law is the father of my spouse; my mother-in-law is the mother of my spouse. If my own parents get divorced and remarry, their new spouses are my stepparents, not my mother-in-law and father-in-law.

The husband of my daughter is my son-in-law; the wife of my son is my daughter-in-law. If my spouse has children from a previous marriage, those are my stepchildren, not sons-in-law or daughters-in-law. I am their stepfather or stepmother, not their father-in-law or mother-in-law.

In these days of more fluid relationships, it is becoming more common to say “daughter-in-law” of the woman my son or daughter has lived with for a long time. On the one hand, that’s a nice way of recognizing long-term relationships that don’t involve a traditional marriage. On the other hand, it’s a bit confusing to use the term “in-LAW” for relationships that are not recognized by law.
Brother-in-Law, Sister-in-Law

These are the only really tricky in-law terms. “Brother-in-law” and “sister-in-law” each have two or three meanings. All authorities agree on the first two meanings, but there is some controversy about the third (and I personally don’t accept it).

My sister-in-law could be:

1. the sister of my spouse, or
2. the wife of my brother, or
3. the wife of my spouse’s brother. (This meaning is accepted by The American Heritage Dictionary of the English Language (Third Edition, 1992), but not by all authorities.)

Similarly, my brother-in-law could be

1. the brother of my spouse, or
2. the husband of my sister, or
3. the husband of my spouse’s sister. (This meaning is accepted by The American Heritage Dictionary of the English Language (Third Edition, 1992), but not by all authorities.)

Consider the following example: Al marries Betty; Betty has a sister Bonnie, who marries Calvin.

Harry = Sally

Al = Betty Bonnie = Calvin

The siblings-in-law:

* Al is Bonnie’s brother-in-law (definition 2), and Bonnie is Al’s sister-in-law (definition 1);
* Betty is Calvin’s sister-in-law (definition 1), and Calvin is Betty’s brother-in-law (definition 2).

So much is agreed. The question is, are Al and Calvin brothers-in-law (definition 3)? Someone once wrote to Ann Landers, the advice columnist, describing this situation. Ann replied: “You are no relation; you are just two men who married sisters.” Though I agree with Ann on this one, I admit that it’s awkward for Al to refer to Calvin as “my wife’s brother-in-law” or “my sister-in-law’s husband”. Probably that’s why Al might refer to Calvin as “my brother-in-law”.

Answer 2

Your Dad's younger brother's wife is his sister in law
