From Middle French consuetude, from Latin cōnsuētūdō (“custom”), from cōnsuēscō (“accustom, habituate; accustom oneself”), corresponding to con- (“with”) + suēscō (“become accustomed”).
consuetude (countable and uncountable, plural consuetudes)
- Custom, familiarity.
- 1819, Walter Scott, Ivanhoe
- “the stain hath become engrained by time and consuetude; let thy reformation be cautious, as it is just and wise.”
Probably borrowed rather than inherited from Latin cōnsuētūdō (“custom”).
