Finally, especially in Europe and societies of European origin, there is Monogamy, that's spelled M-o-n-o-g-a-m-y, Monogamy. Monogamy limits one man to one wife and vice-versa.

The second area of variation is, as we said, the locality of the marriage. Here there seem to be three possibilities, at the husband's home, at the wife's home, or in some new place.

The old term for the arrangement when a wife moves to her husband's family's household is a Patrilocal marriage, that's spelled P-A-T-R-I- L-O-C-A-L, Patrilocal.

A more modern term is Virilocal, and we spell that V-I-R- I-L-O-C- A-L, Virilocal.

The opposite, when the man moves, is termed Matrilocal, and we spell that M-A-T-R-I-L-O-C-A-L, Matrilocal, or Uxorilocal, and that's spelled U-X-O-R-I-L-O-C-A-L, Uxorilocal marriage.

The third possibility when they set up a new household somewhere else is called Neolocal marriage, and that's spelled N-E-O-L-O-C-A-L, Neolocal.
