Dayouth or dayyuth (Arabic: دَيُّوث) is an Arabic-derived term for a person who is apathetic or permissive with regard to adulterous behaviour from a spouse.
[3] The term dayouth has historically held religious, legal and familial implications, depending on time and region, especially if a liaison results in pregnancy.
Arabs of various religions often conceive the concept of the dayouth in a negative light, either personally or scripturally.
[4] The public perception within non-Arab communities that have adopted the notion of the dayouth as a loan-word varies.
This ranges from criticism of its usage as a pejorative being suggestive of acceptance of vain paternalistic gender roles, stigmatization of sexuality or overprotective intrusive sexual gatekeeping within a household and thereby an approval of patronization, to acceptance of its usage in instances where there is an affront to modesty or the archetype of religiously inspired abstinence.
