Dating ex husbands cousin
In English, three sets of terms seem to cause the most difficulty: cousin, in-law, and “half” or “step” relations.
Just to make things messy, each of these terms can correctly be used for several different relationships.
(In Latin they were “avunculus” and “patruus”.) On the other hand, English makes some distinctions that other languages do not.The husband of my daughter is my son-in-law; the wife of my son is my daughter-in-law.
