On the meaning of four French words


Jean-Baptiste Berthelin for the journal Alliance number 103 (1996)


Why we say "beau", speaking of an in-law.






    French words for son-in-law (gendre) and daughter-in-law (bru), respectively from Latin and Germanic origin, are with us from immemorial times. However, other terms for in-laws, using the prefix "beau", are much more recent. We shall examine each of them.

    According to the Petit Robert dictionary, beau-frère appeared in the year 1386. To the present day, this figure is subject to (not always benevolent) stereotypical visions. Here "beau" does not mean "handsome", it has a metaphoric, albeit serious meaning. A brother-in-law is a brother indeed, like a brother at arms. I can think of two reasons for that, and they are related to each other. In Medieval France, fratricide struggles were avoided, so, by extending the notion of brotherhood, one could preserve peace among neighbours. Moreover, the head of a lineage found it advisable to have his sons educated by their maternal uncles. In a much older, matriarcal world, a mother could designate her elder brother as "father" and head of the tribe. Here we find also an educational aspect (less struggles between uncle and nephew than between father and son) and, last but not least, those youngsters could play a role of hostages, preserving the "fraternal peace" among domains. An emblematic case of such brotherhood is given by Roland and Oliver.

    In 1423, enters belle-soeur (sister-in-law). The risk with her is not of war, but of incest. A lady, once married, kept her unmarried sisters as companions, and the Church tried to remind the husbands of the danger, in houses where all people were in their subordination.

    When young and widowed, a belle-mère (mother-in-law) could of course raise similar issues. The dictionary gives no precise date of birth for the word, but a period, "early fifteenth century", that corresponds with the previous one.

    Beau-père, father-in-law, is from 1457, just after the official end of the Middle Ages. This character had a small value among warriors, and a larger one in pacific dynasties of merchants and scholars, brought about by the growth of towns and cities, where older men were no longer deprived of their power and wealth. Also, it means that families no longer merge together to form clans and tribes.

    These remarks are mere musings about familiar terms, leaning on remembrances of a book by Georges Duby, The Knight, the Lady and the Priest, usefully commented by Matt Kuefler of San Diego State University.

    Also, I wrote this from a definitely "patriarcal" point of view, so that all four relations are connecting an adult, married man to other people. Clearly, one should also envision them as used by other members of the nuclear family, as it precisely developed in those medieval times, on the ruins of the former, extensive systems of kinship.
