English: Graphic of the "Iroquois" type of kinship terminology system (one of six main systems commonly recognized by anthropologists).
Note that in some languages with this type of system, the term for father's sister can be the same as that for mother-in-law, and the term for mother's brother the same as father-in-law, while the terms for cross-cousins can be the same as sister-in-law and brother-in-law (or even the same as wife, husband), since cross-cousins (including remote classificatory cross-cousins) are preferred marriage partners, while marriage with parallel cousins is generally strictly prohibited.
